Usage:

The existence of membrane has greatly enhanced the capacity of solid-liquid separation of the system, which results in the substantial increase of the outlet water quality and the volume loading of the system. The water quality after membrane treatment is so high that it even exceeds A level of National Standard Grade One; after disinfection, the final water quality and the high-quality renewable water with high-level of bio-safety may be directly used as new water source. Due to the filtration role of the membrane, the micro-organisms have been completely intercepted in the bioreactor achieving the realization of complete separation between HRT and activated sludge age and elimination of the problem of sludge swelling, which otherwise exists in the traditional activated sludge process. The membrane bioreactor(MBR)has been offered with many outstanding advantages including high removal of pollutants, high efficient nitrification for simultaneous actions of nitrification, denitrification with high removal rate of nitrogen, stabilized effluent quality, less produce of residual sludge, compact structure, less land occupying area(only 1/31/2 the space of the traditional process), easy expansion, high level of automation and easy operation etc.

Membrane bioreactor (MBR) is a kind of new-type high-efficiency wastewater treatment process with combination of high-efficiency membrane separation technology and traditional activated sludge process. With unique structured submerged type membrane module, the equipment is put in the aeration tank; after aerobic aeration and biological treatment, the water is pumped through the filter membrane and flows out. MBR process has big the difference as compared with the traditional wastewater treatment process as MBR takes the place of the secondary sedimentation tank and tertiary treatment process in the traditional biological process.

Used for sewage treatment,and the treated effluent can meet the quality of reclaimed water.
