Ozonasi: Contoh Aplikasi Industri

Kinerja OzonasiKinerja Ozonasi Removal of COD by ozonation is basically feasible. Higher COD removal

performance is possible with ozonation processes provided pre-treatmentby sand filtration and post-treatment using activated carbon or abiological filtration process are employed. Higher rates of removal arepossible using Ozone–Hydrogen peroxide treatment.

Less than 10 degrees of chromaticity are possible at an ozone dosage of5 to 10 mg/L or more.

Efficient deodorization takes place in parallel with decoloration anddisinfection.

Two-log or higher inactivation of coliform bacteria is possible at around 5–10 mg/L or more of ozone dosage and around 10 minutes of reactiontime. This treatment can achieve the lower than the 3,000/cm3 ofcoliform bacteria designated in the technological standards for treatedwastewater quality provided in the Sewerage Law.

Many micropollutants, such endocrine-disrupting chemicals, can beremoved at rates exceeding 90% at doses of around 5 mg/L or more ofozone. An advanced oxidation process combined with ozone canachieve even better removal performance.

Perancangan Sistem OzonasiPerancangan Sistem Ozonasi

Design and operational parameters such as ozone dosage, andthe components of treatment process should be matched to theconditions of target substances and target treated water qualitymeeting.

The components of treatment facilities including systemswith/without pretreatment and post-treatment should bematched to the expected treatment performance, and cost-effectiveness matching the water quality of the inflow, thepurposes of ozonation, the target treated water quality andthe target user’s needs.

In Ozone-Hydrogen peroxide treatment, the configuration ofthe reactor and its design and operational parameters (ratioof ozone to hydrogen peroxide and concentration ofdissolved ozone) should be fine-tuned to achieve the mostefficient oxidizing.

Operasi dan Perawatan Sistem OzonasiOperasi dan Perawatan Sistem Ozonasi

Analysis of ozone absorption efficiency, inlet water quality and treated water quality. Regular inspections and maintenance of equipment are needed to operate and maintain it efficiently and effectively.It is recommended to keep monitoring not only the concentration of ozone at the plant, but that nearby and that of residual ozone in the effluent.
