MBR membrane module- New technology for wastewater treatment

Membrane Bio-Reactor (MBR) is a new type of wastewater treatment system that combines membrane separation technology with biological treatment technology.

Replacing the traditional biological treatment technology terminal secondary sedimentation tank with membrane module, maintaining high activated sludge concentration in the bioreactor, increasing the biological treatment organic load, thereby reducing the sewage treatment facility footprint, and reducing residual pollution by maintaining low sludge load Mud amount. The activated sludge and macromolecular organic matter in the tank are mainly intercepted by a membrane separation device immersed in an aerobic biological pool. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased by 8000~10,000mg/L or even higher; the sludge age (SRT) can be extended to more than 30 days.

Membrane bioreactor can retain the microorganisms with long generation period due to its effective retention, and can realize deep purification of sewage. At the same time, nitrifying bacteria can fully reproduce in the system, and its nitrification effect is obvious, which provides the possibility of deep phosphorus removal and nitrogen removal.
