AnaEG has been developed based on the third generation of high efficient anaerobic reactor EGSB(Expanded Granular Sludge Bed).

AnaEG

AnaEG integrates Hydrolytic -Acidogenic step and methanogenic step in one reactor.Unique design of gas-water-solid separator High ratio of height to diameterAcid -producing bacteria and methane- producing bacteria grow respectively in the lower and upper area. Formation of granular sludge Granular sludge do not expand in acid-producing zone, while Granular sludge in methane-producing zone expand with biogas bubbling.

Less foot-print

Intensification of hydraulic mixingInfluent pH needn’t control strictly

High biomass Improvement of substrate-biomass contact High efficiency

AnaEG has been widely applied to the treatment of corn ethanol producing wastewater, alcohol wastewater, starch wastewater, brewery wastewater, etc..

MBS is a biological products. The functional bacteria are mixed with some kind of poison-free polymers at

proper ratio and fixed inside the web structure of polymer molecular chains by adding cross linking agents.

The polymer selected must possess high biological , chemical and mechanical stability.

The three dimensional nano-scale structure of polymer chain makes mass transfer easier between the bulk

liquid and the cells within it, which also facilitate the proliferation of

microbes and stimulation of their activity. In most cases, the pellets are

shaped into 3*3*3 mm3 pellets . The density of the pellets is similar to water.

Acclimated in ammonia wastewater, the nitrifier tend to be rich near the

surface of pellets and the denitrifier grow inside.

Now MBS has been successfully applied in not only high strength

ammonia and organic wastewater, but also micro-polluted water treatment.
