Membrane Bio-Reactor (MBR) is a new form of wastewater treatment system that organically combines membrane separation technology and biological treatment technology. It replaces the secondary sedimentation tank which occupies a large area in the traditional activated sludge system. It uses the membrane separation equipment immersed in the aerobic biological tank to intercept the activated sludge and macromolecular solids in the tank. The concentration of activated sludge (MLSS) can reach more than 10g/L, and the sludge age (SRT) can be extended for more than 30 days, Such a high concentration system has greatly reduced the volume of the biological reaction tank and the amount of construction work, and the quality of the produced water can meet the Class A standard of the international GB8978-1996 comprehensive sewage discharge, which becomes the best choice for sewage treatment and water resources recycling in the 21st century.

Performance characteristics

1. The water quality of the effluent meets the international Class A standard and can be reused as reclaimed water

2. Easy to operate and realize automatic control

3. Compared with the traditional secondary sedimentation tank process, it covers a small area

4. Short hydraulic retention time, long sludge discharge period, better separation effect

Scope of application

1. Reclaimed water reuse:

2. Hospital wastewater treatment

3. Washing wastewater treatment

4. Food wastewater treatment

5. Municipal and domestic sewage treatment

6. Upgrading and reconstruction of traditional sewage process projects
