Secondary settling tank, a traditional biological treatment technology, is replaced by membrane modules. A high sludge concentration is maintained in the bioreactor; organic loading of biological treatment is improved, thus reducing the floor area of wastewater treatment facilities. Besides, the surplus sludge volume is reduced by keeping a low sludge loading. In the membrane bioreactor system, the concentration of activated sludge (MLSS) can be up to 800010,000 mg/L, or even higher; sludge age (SRT) can be extended to more than 30 days.
Morlans can combine oxygen-enriched aeration technology with MBR reactor, further improve the sludge concentration and realize the simultaneous removal of COD, ammonia nitrogen and SS as well as the sludge aerobic digestion in the same reactor. Morlans has created good conditions for advanced wastewater treatment. Small and medium sized projects can realize equipment integration through MBR technology.
