11 About the TEQUATICtrade PLUS Fine Particle Filter
The TEQUATICtrade PLUS fine particle filter with its innovative and patented design
combines the power of continuously cleaning cross-flow filtration with centrifugal
separation and solids collection into one device The TEQUATIC PLUS filter is designed
to process a wide range of difficult-to-treat feedwaters with very high or highly
variable total suspended solids (TSS) It provides a cost-effective reliable solution to
traditional filtration technologies facilitating high uptime consistent performance
and a smaller footprint A smaller footprint can be achieved for example via high
water recovery (typically gt99) less disposal of consumables less space required and
low to no chemical use
The TEQUATIC PLUS filter is ideal
bull In applications ranging from nonpotable industrial wastewater treatment and reuse
(such as food and beverage pulp and paper and textiles and laundry) to produced
water for oil and gas to power generation
bull As a primary lter a prelter for ultraltration (UF) and reverse osmosis (RO) and
as a postlter following water reuse technologies like moving bed bioreactor (MBBR)
and dissolved air otation (DAF)
bull As an alternative or a complement to traditional ltration systems
Key components of the technology include
bull Self-propelled cleaning assembly (non-motorized)
bull Cross-ow ltration of lighter solids
bull Solids collection chamber that removes particles in real time within
the recirculation loop
bull Centrifugal separation for heavy particle removal
The TEQUATIC PLUS fine particle filter combines the capabilities of many filtration
technologies into one unit The filter tolerates very high and highly variable TSS of up
to 10000 mgL Typical uptimes are gt99 due to continuous filtrate and minimal filter
fouling The high uptime can result in low operational expense

12 Filter Process
1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

11 About the TEQUATICtrade PLUS Fine Particle Filter
The TEQUATICtrade PLUS fine particle filter with its innovative and patented design
combines the power of continuously cleaning cross-flow filtration with centrifugal
separation and solids collection into one device The TEQUATIC PLUS filter is designed
to process a wide range of difficult-to-treat feedwaters with very high or highly
variable total suspended solids (TSS) It provides a cost-effective reliable solution to
traditional filtration technologies facilitating high uptime consistent performance
and a smaller footprint A smaller footprint can be achieved for example via high
water recovery (typically gt99) less disposal of consumables less space required and
low to no chemical use
The TEQUATIC PLUS filter is ideal
bull In applications ranging from nonpotable industrial wastewater treatment and reuse
(such as food and beverage pulp and paper and textiles and laundry) to produced
water for oil and gas to power generation
bull As a primary lter a prelter for ultraltration (UF) and reverse osmosis (RO) and
as a postlter following water reuse technologies like moving bed bioreactor (MBBR)
and dissolved air otation (DAF)
bull As an alternative or a complement to traditional ltration systems
Key components of the technology include
bull Self-propelled cleaning assembly (non-motorized)
bull Cross-ow ltration of lighter solids
bull Solids collection chamber that removes particles in real time within
the recirculation loop
bull Centrifugal separation for heavy particle removal
The TEQUATIC PLUS fine particle filter combines the capabilities of many filtration
technologies into one unit The filter tolerates very high and highly variable TSS of up
to 10000 mgL Typical uptimes are gt99 due to continuous filtrate and minimal filter
fouling The high uptime can result in low operational expense

12 Filter Process
1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

11 About the TEQUATICtrade PLUS Fine Particle Filter
The TEQUATICtrade PLUS fine particle filter with its innovative and patented design
combines the power of continuously cleaning cross-flow filtration with centrifugal
separation and solids collection into one device The TEQUATIC PLUS filter is designed
to process a wide range of difficult-to-treat feedwaters with very high or highly
variable total suspended solids (TSS) It provides a cost-effective reliable solution to
traditional filtration technologies facilitating high uptime consistent performance
and a smaller footprint A smaller footprint can be achieved for example via high
water recovery (typically gt99) less disposal of consumables less space required and
low to no chemical use
The TEQUATIC PLUS filter is ideal
bull In applications ranging from nonpotable industrial wastewater treatment and reuse
(such as food and beverage pulp and paper and textiles and laundry) to produced
water for oil and gas to power generation
bull As a primary lter a prelter for ultraltration (UF) and reverse osmosis (RO) and
as a postlter following water reuse technologies like moving bed bioreactor (MBBR)
and dissolved air otation (DAF)
bull As an alternative or a complement to traditional ltration systems
Key components of the technology include
bull Self-propelled cleaning assembly (non-motorized)
bull Cross-ow ltration of lighter solids
bull Solids collection chamber that removes particles in real time within
the recirculation loop
bull Centrifugal separation for heavy particle removal
The TEQUATIC PLUS fine particle filter combines the capabilities of many filtration
technologies into one unit The filter tolerates very high and highly variable TSS of up
to 10000 mgL Typical uptimes are gt99 due to continuous filtrate and minimal filter
fouling The high uptime can result in low operational expense

12 Filter Process
1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

11 About the TEQUATICtrade PLUS Fine Particle Filter
The TEQUATICtrade PLUS fine particle filter with its innovative and patented design
combines the power of continuously cleaning cross-flow filtration with centrifugal
separation and solids collection into one device The TEQUATIC PLUS filter is designed
to process a wide range of difficult-to-treat feedwaters with very high or highly
variable total suspended solids (TSS) It provides a cost-effective reliable solution to
traditional filtration technologies facilitating high uptime consistent performance
and a smaller footprint A smaller footprint can be achieved for example via high
water recovery (typically gt99) less disposal of consumables less space required and
low to no chemical use
The TEQUATIC PLUS filter is ideal
bull In applications ranging from nonpotable industrial wastewater treatment and reuse
(such as food and beverage pulp and paper and textiles and laundry) to produced
water for oil and gas to power generation
bull As a primary lter a prelter for ultraltration (UF) and reverse osmosis (RO) and
as a postlter following water reuse technologies like moving bed bioreactor (MBBR)
and dissolved air otation (DAF)
bull As an alternative or a complement to traditional ltration systems
Key components of the technology include
bull Self-propelled cleaning assembly (non-motorized)
bull Cross-ow ltration of lighter solids
bull Solids collection chamber that removes particles in real time within
the recirculation loop
bull Centrifugal separation for heavy particle removal
The TEQUATIC PLUS fine particle filter combines the capabilities of many filtration
technologies into one unit The filter tolerates very high and highly variable TSS of up
to 10000 mgL Typical uptimes are gt99 due to continuous filtrate and minimal filter
fouling The high uptime can result in low operational expense

12 Filter Process
1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

o TEMPERATURE STABLE
The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

11 About the TEQUATICtrade PLUS Fine Particle Filter
The TEQUATICtrade PLUS fine particle filter with its innovative and patented design
combines the power of continuously cleaning cross-flow filtration with centrifugal
separation and solids collection into one device The TEQUATIC PLUS filter is designed
to process a wide range of difficult-to-treat feedwaters with very high or highly
variable total suspended solids (TSS) It provides a cost-effective reliable solution to
traditional filtration technologies facilitating high uptime consistent performance
and a smaller footprint A smaller footprint can be achieved for example via high
water recovery (typically gt99) less disposal of consumables less space required and
low to no chemical use
The TEQUATIC PLUS filter is ideal
bull In applications ranging from nonpotable industrial wastewater treatment and reuse
(such as food and beverage pulp and paper and textiles and laundry) to produced
water for oil and gas to power generation
bull As a primary lter a prelter for ultraltration (UF) and reverse osmosis (RO) and
as a postlter following water reuse technologies like moving bed bioreactor (MBBR)
and dissolved air otation (DAF)
bull As an alternative or a complement to traditional ltration systems
Key components of the technology include
bull Self-propelled cleaning assembly (non-motorized)
bull Cross-ow ltration of lighter solids
bull Solids collection chamber that removes particles in real time within
the recirculation loop
bull Centrifugal separation for heavy particle removal
The TEQUATIC PLUS fine particle filter combines the capabilities of many filtration
technologies into one unit The filter tolerates very high and highly variable TSS of up
to 10000 mgL Typical uptimes are gt99 due to continuous filtrate and minimal filter
fouling The high uptime can result in low operational expense

12 Filter Process
1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

1 Feedwater enters the unit Centrifugal force pushes heavy particles outward Lighter solids are removed by cross-ow ltration
Filtered water exits as ltrate
2 The vortex chamber houses the lter unit which continuously cleans the lter Filter cut-os are from 10ndash50 μm Pressure drop
across the filter is typically lt1 psi
3 Solids enter the recirculation and solids collection chamber Other particles flow into the recirculation line
4 Solids settle at the bottom in the collection chamber and are purged as concentrate for disposal or further processing Unit
recovery is typically gt99 minimizing disposal volumes

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

o TEMPERATURE STABLE
The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Inspect clean or replace sensor Verify that there is
not excessive air in the system or housing
Differential pressure 00 psi
Flow across filter too low to cause a
measurable differential pressure drop
Verify that sensor connections are connected to
the correct port Check that the feedwater pump
is operating
Breach in filter element Replace filter element
No filtrate flow
Filtrate valve closed Open filtrate valve
Insufficient feedwater flow Ensure feed pump is operating
Plugged filter Should see high differen-
tial pressure if sensor is working properly
Initiate Zero DP Clean cycle first if not adequate
replace filter element andor filter assembly or manu-
ally remove filter element and clean
Insufficient recirculat ion flow rate Ensure recirculat ion pump is operating
Excessive noise from filter
Air in system Vent air from system
Cleaning assembly making contact with
housing or fil terVerify that cleaning assembly is installed correctly
Filter does not return to ldquocleanrdquo differential pressure

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 Inspect the outside of the shipping container for evidence of damage If damage is
evident contact your supplier
2 The TEQUATICtrade PLUS filter cleaning assembly filter assembly and filter adaptor
will be pre-assembled and packaged separate from the housing ( Figure 25)
Remove these components from the packaging and check them against the
shipping manifest Figure 26 defines the identification numbers on the filter
3 The TEQUATIC PLUS filter housing will be mounted to the base of the shipping
container in a horizontal or vertical position Remove the mounting bolts
4 Lift and handle the housing carefully using suitable lifting equipment and the
lifting points provided ( Figure 27 ) The product must be securely harnessed for
lifting and handling and all accident prevention regulations must be observed

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

o TEMPERATURE STABLE
The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Normal In normal operation raw water can be pumped to parallel TEQUATICtrade Plus filters with each filter connected as a mani-
fold to the feed line As filtrate is being produced each individual filter will go into Zero DP Clean and Purge cycles as set up in the
controls on a time basis Additional concentrate flow can be sent back to the raw water tank This will provide higher flow at the
inlet and higher cleaning assembly rotational speed around the filter It also allows the solids concentration to reach a steady state vs continually concentrating until purged
Standby If filtrate is no longer needed for the process (for example filtrate tank is full or raw water tank is low) the feed pump
can continue to run (Individual recirculation pumps should also continue to run) With the individual auto actuated filtrate valves
closed raw water will be pumped through the continuous concentrate line back to the raw water tank
Shutdown Shut down the system for maintenance or troubleshooting Maintenance includes replacement of filter and cleaning
assembly Avoid shutting down the system for brief disruptions in the process Instead operate in standby mode with the existing
water recirculating back to the raw water tank or with just the recirculation pumps running
Flushing (Closed Loop) Similar to Standby mode a flush system is recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Flushing diverts ltered water through the system which
can be sent back to the raw water source
Cleaning (Open Loop with Purge) Clean in Place (CIP) loops are recommended for processes where solids tend to build up on
the cleaning assembly or internal components in the housing or system Cleaning diverts filtered water through the system and
can be combined with chemical dosing to more effectively remove particle build-up The chemically dosed filtered water can be
recirculated internally and periodically flushed to drain

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

bull Perform Zero DP Clean combined
with purges if the differential
pressure exceeds 25 psi If frequent
high differential pressure events
occur reduce filtrate flow
bull Operating with the cleaning
assembly rotational speed outside
of the specified range can result in
damage to the equipment premature
failure or performance loss
bull Operating with dierential pressures
above the specified range can result in
damage to the equipment premature
failure or performance loss
bull Do not start producing ltrate until
the cleaning assembly rotational
speed is verified
bull Producing ltrate without proper
cleaning assembly rotation will resultin premature failure

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

43 Installing Cleaning Assembly and Filter Adaptor
1 Slide the cleaning assembly over the filter assembly and spin the cleaning assembly
clockwise Ensure that the cleaning assembly can rotate freely around the filter
2 The filter adaptor mounts to the top of the filter assembly with locking grooves
Lubricate the seals with silicone or white grease and insert the filter adaptor evenly
into the filter assembly rotating clockwise It should slide into place without
excessive force rotating clockwise approximately 20 degrees and locking in Make
sure the adaptor is properly seated
Important
Do not attempt to assemble the

44 Securing Housing Lid
1 Make sure the housing seal of the TEQUATICtrade PLUS filter is clean lubricated with silicone or white grease and properly
positioned in the seal groove of the lid before securing the lid
2 Using the alignment pins lower lid and hand-tighten swing bolts ( Figure 30)
3 Tighten swing bolts rst to approximately 40 ft-lb of torque at opposite ends of the circular face For example assuming the rst
one is at the ldquo1rdquo position tighten in the following order (1 2) (3 4) etc as shown in Figure 30
4 Following the same order tighten the swing bolts to approximately 80 ft-lb of torque To avoid damaging the housing do not
exceed 80 ft-lb

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

The EPPHS sensors provide one digital output that is normally OFF and turns ON when a magnetic field is present Note thatOUTPUT ON means LOW for NPN sensors and HIGH for PNP sensors The EPPHS is a programmable Hall Effect sensor which willtrigger from either magnetic pole at the programmed gap
The distance between the sensor face and either pole of a magnet that operates the switch (turns the output transistor on) is referred toas the Operate Air Gap This gap is determined by looking at the magnets flux density vs air gap curve The distance that producesthe magnetic field equal to or less than Release Point specified on this sheet is the Release air gap The must operate air gap is thedistance at which the magnet produces a field equal to the MAX operate point of the Hall switch The must release gap is the distancethe at which the magnet produces a field equal to the MIN release point Note that magnets produce weaker fields as the temperatureincreases
In addition to the EPPHS we offer a variety of South Pole and Either pole Hall Effect and Magnetoresistive sensors including multipleprogrammable sensors North and South Pole output sensors latching sensors and sensors with speedcount and direction outputsCheck our website or contact us to discuss all of our magnetic speed count and position detection sensors

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

71 Problems Causes and Solutions
Table 13 lists possible problems during operation of the TEQUATICtrade PLUS filter and suggested solutions
Table 13 Troubleshooting problems causes and solutions
Problem Possible Cause Solution
Increasing differential pressure(should be at approximately 05 psi at steady run state)
Cleaning assembly worn Replace cleaning assembly
Incoming water quality upsetInitiate Zero DP Clean cycle Check incoming water
quality Remove filter element and manually clean
Filtrate volume too high for desired water
qualityAdjust filtrate flow rate
Cleaning assembly not spinning or too
slow for desired water quality
Ensure cleaning assembly is spinning and clean-
ing assembly rotational speed is adequate for water
quality Increase recirculation flow rate
Recirculation loop concentrated too high
for desired water quality
Increase concentrate purge frequency andor purge
duration
Problem with differential pressure
sensor
Inspect clean or replace sensor Verify that there is
not excessive air in the system or housing
Differential pressure 00 psi
Flow across filter too low to cause a
measurable differential pressure drop
Verify that sensor connections are connected to
the correct port Check that the feedwater pump
is operating
Breach in filter element Replace filter element
No filtrate flow
Filtrate valve closed Open filtrate valve
Insufficient feedwater flow Ensure feed pump is operating
Plugged filter Should see high differen-
tial pressure if sensor is working properly
Initiate Zero DP Clean cycle first if not adequate
replace filter element andor filter assembly or manu-
ally remove filter element and clean
Insufficient recirculat ion flow rate Ensure recirculat ion pump is operating
Excessive noise from filter
Air in system Vent air from system
Cleaning assembly making contact with
housing or fil terVerify that cleaning assembly is installed correctly
Filter does not return to ldquocleanrdquo differential pressure
after Zero DP Clean
Filter getting excessively dirty due to
quality of water
Replace filter element andor filter assembly or
manually remove filter element and clean
Water leaking from housing seal Housing seal damaged or aged Replace housing seal
Water leaking from housing connection
Groove lock gasket in Victaulic clamp
worn or not installed properly or Victau-
lic clamp not tightened properly

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

42 Installing Housing and Filter Assembly
1 Secure the TEQUATICtrade PLUS filter housing to a mounting plate or bracket with bolts Ensure that the mounting plate can
support the weight of the TEQUATIC PLUS filter listed in the Table 7 Note the TEQUATIC PLUS filter must be mounted vertically
with the filtrate piping facing straight up
2 Loosen swing bolts and remove the lid of the TEQUATIC PLUS filter by lifting up
3 The bearing and bayonet mounts will already be installed in the filter assembly with two washers for each bayonet mount
( Figure 28a and b) Check that they have not come loose during shipment
4 The filter assembly mounts to the vortex plate ( Figure 28c and d) Insert the three bayonet mounts into the three slots in the
vortex plate and rotate clockwise (in the direction of flow)

43 Installing Cleaning Assembly and Filter Adaptor
1 Slide the cleaning assembly over the filter assembly and spin the cleaning assembly
clockwise Ensure that the cleaning assembly can rotate freely around the filter
2 The filter adaptor mounts to the top of the filter assembly with locking grooves
Lubricate the seals with silicone or white grease and insert the filter adaptor evenly
into the filter assembly rotating clockwise It should slide into place without
excessive force rotating clockwise approximately 20 degrees and locking in Make
sure the adaptor is properly seated
Important
Do not attempt to assemble the

44 Securing Housing Lid
1 Make sure the housing seal of the TEQUATICtrade PLUS filter is clean lubricated with silicone or white grease and properly
positioned in the seal groove of the lid before securing the lid
2 Using the alignment pins lower lid and hand-tighten swing bolts ( Figure 30)
3 Tighten swing bolts rst to approximately 40 ft-lb of torque at opposite ends of the circular face For example assuming the rst
one is at the ldquo1rdquo position tighten in the following order (1 2) (3 4) etc as shown in Figure 30
4 Following the same order tighten the swing bolts to approximately 80 ft-lb of torque To avoid damaging the housing do not
exceed 80 ft-lb

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

bull Perform Zero DP Clean combined
with purges if the differential
pressure exceeds 25 psi If frequent
high differential pressure events
occur reduce filtrate flow
bull Operating with the cleaning

of the specified range can result in
damage to the equipment premature
failure or performance loss
bull Operating with dierential pressures
above the specified range can result in
damage to the equipment premature
failure or performance loss

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

33 Critical Measurements
There are two critical measurements needed to monitor operation of the TEQUATICtrade PLUS filter
bull Differential Pressure is measured across the filter and is used to determine several operating parameters including filtrate
flow rate and frequency of Zero DP Cleans The TEQUATIC PLUS filter operates at low differential pressures with typical values
ranging from 025 to 045 psi These lower pressure values should remain relatively stable Higher dierential pressures indicate
that the filter is being fouled with suspended particles If the differential pressure does not decrease after closing the filtrate
valve this could indicate that the cleaning assembly or filter needs to be replaced or cleaned If the cleaning assembly and filter
are relatively new but the system experiences frequent high differential pressure events this is most likely due to nonoptimal
operating conditions The filtrate flow should be decreased to provide the highest flow at a low and stable differential pressure
bull Cleaning Assembly Rotational Speed (rpm) is measured with a magnetic sensor that picks up a signal from a magnet that is
installed in the cleaning assembly This measurement verifies that the cleaning assembly is spinning It is important to confirm
that the rotational speed is within the specified range The rotational speed of the cleaning assembly should remain stable
and be within the speed ranges described in the Startup and Operation section Higher speeds could indicate that the cleaning
assembly is worn and not making sufficient contact with the filter If this occurs the cleaning assembly should be replaced
Lower speeds are most likely caused by insufficient flow or velocity at the inlet of the TEQUATIC PLUS filter
Depending on the application additional instrumentation to measure parameters like temperature flow pressure TSS
and turbidity should be considered The TEQUATIC PLUS filter is used in a wide variety of industrial applications as either
pretreatment to other processes or as stand-alone filtration In a pretreatment design using the minimum number of critical
measurements is most cost-eective and easiest to integrate For a stand-alone application additional measurements might be
necessary to adequately evaluate system performance

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi

into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

45 Installing Piping and Recirculation Pump Connections
1 All connections use IPS groove (Victaulic) style couplings (not included) Always
lubricate clamping seals with silicone or white grease
2 Connect a pressurized water source to the inlet feed connection of the TEQUATICtrade
PLUS filter Use flexible lines that can be easily removed for future maintenance
Inlet pressure should not exceed 100 psi Always open valves slowly Recommended
Feedwater should be regulated to provide constant pressure (either with a variable
frequency motor drive or with a mechanical pressure regulator)
3 Connect the filtrate line to a product storage tank or a downstream process Use
flexible lines that can be easily removed for future maintenance Connect in such
a way as to minimize static back pressure (le2 psi) Avoid static ltrate-side back
pressure at all times
4 Connect the recirculation line back into the feed line and tee into the feed just
upstream of the inlet connection ( Figure 31)
Important
bull Do not have more than 2 psi
back pressure across the filterbull Avoid static ltrate-side back
pressure at all times

5 Connect the concentrate purge line to an open drain to prevent back pressure In
some applications the concentrate can be connected back to the source water to
increase system water recovery6 Make sure that the installation location allows for access to all swing bolts and takes
into consideration maintenance requirements such as space for taking the lid on and
off (or using a lifting device to remove the lid) and installing replacement components
7 Recommended Use flexible hose connections to and f rom the TEQUATICtrade PLUS filter
Do not install any rigid piping connections to the housing
8 Connections to the TEQUATIC PLUS filter have a 0030-inch tolerance for alignment
9 Design interconnecting pipe to include piping supports Support interconnecting
piping so that it is self-supporting To avoid damaging the housing or connections the
total weight of piping run and fittings supported by the housing should not exceed 5 lb
Important
bull Piping must be independently
supported
bull Do not exceed 5 lb load on the
housing

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

47 Installing Auto Actuated Valves
1 Install auto actuated valves (not included) in the filtrate and concentrate lines See Figure 3
2 Install the valves as close to the connection point as possible
3 Valve material should be compatible with uid that it will contact (ie aggressive industrial water sources)
4 Recommended Use a motor-actuated valve not a solenoid valve A motor-actuated valve will open and close
slower than a solenoid valve This will help minimize water hammer
48 Installing Manual Valves
1 A diaphragm valve should be installed close to the filtrate connection point to control flow See Figure 3
2 A check valve must be installed on the filtrate line to prevent backflow
3 If the recirculation pump is installed to pressurize the feed a diaphragm valve should be installed to regulate the recirculation
flow Install the valve close to the recirculation connection point
4 A manual drain valve should be installed on the concentrate line
5 Air relief valves should be installed at high points in the system such as the differential pressure input ports
Note No valves are included

1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

51 Startup and Operation
1 Make sure filtrate and concentrate lines are closed
2 Fill system with water Purge air out of the system by opening the air relief valve
3 Once all air is expelled from the system run the system in Zero DP Clean mode
Filtrate valve is closed concentrate purge valve is closed and recirculation pump is on
4 With the filtrate valve closed verify that the cleaning assembly is spinning at the
specified rotational speed Allow system to reach steady state
5 Monitor the differential pressure and slowly open filtrate valve which will allow
feedwater to flow into the system System is now in Normal mode The filtrate line
is open and producing water the recirculation pump is on and the concentrate
purge valve is closed
6 Verify dierential pressure is not above specied range Typical initial dierential
pressure is between 025 and 045 psi

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

NOTES Periodically purge the concentrate on a time basis (for example every 5 to 15 min for approximately 5 s) This is a
momentary opening and closing of the concentrate auto actuated valve During the purge a volume of water in the housing will
be displaced depending on the model in use (F-50 = 1ndash2 gal F-75 = 8ndash12 gal F-150 = 70ndash90 gal)
If the feedwater has problematic or high concentration of solids a continuous concentrate purge is recommended The continuous
flow can return back to the feedwater tank This will create a steady-state concentration within the housing and increase cleaning
assembly rotational speed (rpm)
If a continuous concentrate purge is implemented make sure the continuous concentrate pipeline connects to the feedwater tank
at a point higher than the feedwater inlet and that the feedwater tank level is always higher than the feedwater inlet If this is not
possible an additional auto actuated valve will need to be installed on the continuous concentrate line and will close if there is no
feedwater being supplied to the system ( Figure 6)
Perform periodic Zero DP Cleans on a time basis (for example every 1 to 3 h for approximately 60 s)
To prevent potential solids build-up inside the unit it is recommended to keep the water moving through the system Avoid
system shutdowns except in cases of filter replacement or maintenance When the process does not require filtrate run the system
in STANDBY mode where the recirculation pump continues to run and optionally the feed pump can continue to run with water
purging through the unit and returning to the feed source tank
If the feedwater has problematic or high concentration of solids combine Zero DP Clean and Concentrate Purges periodically into
one step so the filter is being cleaned while concentrate is being purged at the same time The Concentrate Purge should occur at the
beginning of the Zero DP Clean cycle Extending Concentrate Purge durations and Zero DP Clean durations will help clean the screen

52 Data Logging
1 Keep a log of the system operation An example is shown in Figure 35
2 After initial startup data should be collected several times a day to verify the
system is operating as intended
3 If there are any outstanding fluctuations in the initial performance such as
unstable or rising differential pressure operating conditions or system design
should be adjusted (ie lowering the ltrate ow rate) until system stabilizes and
can run continuously
4 Once optimum operating conditions are established data should continue to be
collected at least once per day

Table 13 Troubleshooting problems causes and solutions
Problem Possible Cause Solution
Increasing differential pressure(should be at approximately 05 psi at steady run state)
Cleaning assembly worn Replace cleaning assembly
Incoming water quality upsetInitiate Zero DP Clean cycle Check incoming water
quality Remove filter element and manually clean
Filtrate volume too high for desired water
qualityAdjust filtrate flow rate
Cleaning assembly not spinning or too
slow for desired water quality
Ensure cleaning assembly is spinning and clean-
ing assembly rotational speed is adequate for water
quality Increase recirculation flow rate
Recirculation loop concentrated too high
for desired water quality
Increase concentrate purge frequency andor purge
duration
Problem with differential pressure
sensor
Inspect clean or replace sensor Verify that there is
not excessive air in the system or housing
Differential pressure 00 psi
Flow across filter too low to cause a
measurable differential pressure drop
Verify that sensor connections are connected to
the correct port Check that the feedwater pump
is operating
Breach in filter element Replace filter element
No filtrate flow
Filtrate valve closed Open filtrate valve
Insufficient feedwater flow Ensure feed pump is operating
Plugged filter Should see high differen-
tial pressure if sensor is working properly
Initiate Zero DP Clean cycle first if not adequate
replace filter element andor filter assembly or manu-
ally remove filter element and clean
Insufficient recirculat ion flow rate Ensure recirculat ion pump is operating
Excessive noise from filter
Air in system Vent air from system
Cleaning assembly making contact with
housing or fil terVerify that cleaning assembly is installed correctly
Filter does not return to ldquocleanrdquo differential pressure
after Zero DP Clean
Filter getting excessively dirty due to
quality of water
Replace filter element andor filter assembly or
manually remove filter element and clean
Water leaking from housing seal Housing seal damaged or aged Replace housing seal
