The MBR membrane bioreactor

  Membrane bioreactor (be Bio - Reactor, MBR) as the organic combination of Membrane separation technology and biological treatment technology of a new type wastewater treatment system. With membrane module to replace the traditional biological treatment technology at the end of the second pond, keep highly active sludge concentration in the bioreactor, improve the biological treatment of organic load, thus reducing sewage treatment facilities area, and by keeping low sludge loading to reduce excess sludge. Mainly using the immersed in aerobic biological pool of membrane separation equipment intercept slot activated sludge and macromolecular organic matter. In activated sludge membrane bioreactor system (MLSS) concentration can be up to 8000 ~ 8000 mg/L, or even higher; Sludge age (SRT) can be extended to more than 30 days.
   Interception of membrane bioreactor due to its effective role, may retain generation cycle longer microbes, which can realize on the depth of water purification, denitrifying bacteria in the system can fully reproduce at the same time, the nitrification effect is obvious, the depth of possible biological nutrient removal.
