Membrane bio-reactor

Membrane - bioreactor (Membrane Bio-Reactor, MBR) is a membrane separation technology and new patterns of biological treatment of organic wastewater treatment system combines it. Biological treatment with membrane technology to replace the traditional end of the secondary settling tank, to maintain a high concentration of activated sludge in the bioreactor, increase the biological treatment of organic load, thereby reducing the area of sewage treatment facilities, and by keeping a low sludge load reduce the residual pollution mud. The main advantage of membrane separation equipment sludge trapped in water and organic molecules. Inner membrane bioreactor system activated sludge (MLSS) concentration can be increased to 8000 ~ 10,000mg / L, or even higher; SRT (SRT) may be extended to 30 days.
Membrane bioreactor effectively retain its role, may be retained longer generation time of microorganisms can be achieved for wastewater purification, simultaneous nitrification bacteria in the system can fully reproduce, nitrification effect is obvious, phosphorus and nitrogen removal for possible depth .
