Membrane Bio-Reactor (MBR) is a new type of wastewater treatment system that combines membrane separation technology and biological treatment technology.
The membrane module replaces the traditional biological treatment technology end of the secondary sedimentation tank, maintains a high concentration of activated sludge in the bioreactor, improves the organic load of biological treatment, thus reduces the footprint of wastewater treatment facilities, and reduces the amount of residual sludge by maintaining a low sludge load. Membrane separation equipment is primarily utilized to retain activated sludge and macromolecular organic matter in the water. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased to 8,000~10,000mg/L or even higher; the sludge age (SRT) can be extended to more than 30 days.
Membrane bioreactor because of its effective retention effect, can retain the generation cycle of microorganisms, can realize the depth of sewage purification, at the same time, nitrifying bacteria in the system can be fully reproduced, its nitrification effect is obvious, the depth of phosphorus denitrification to provide the possibility.
