Bio-reactor membrane sheets with the material of PVDF Lining-added enhanced hollow fiber membrane

In the field of sewage treatment and water reuse, MBR, also known as Membrane Bio-Reactor (Membrane Bio-Reactor), is a new type of water treatment technology that combines a membrane separation unit and a biological treatment unit.
Membrane bioreactor (MBR) technology is a new type of sewage treatment technology that combines high-efficiency membrane separation technology and activated sludge method. The membrane unit is directly immersed in the mixed liquid of activated sludge and water. There is no need to set up a secondary settling tank after the biochemical tank, and there is no need to set up a subsequent filtration system, thus reducing the area occupied, and it is a modern and efficient water treatment system , Which can meet the increasing demand of industrial and municipal sewage treatment volume, and greatly improve the water quality after advanced sewage treatment.

The Introduction of Membrane Bio-Reactor

Membrane Bio-Reactor (Membrane Bio-Reactor, MBR) is a new type of wastewater treatment system that combines membrane separation technology and biological treatment technology. Substituting membrane modules to replace the secondary sedimentation tank at the end of the traditional biological treatment technology, maintaining a high concentration of activated sludge in the bioreactor, increasing the organic load of biological treatment, thereby reducing the footprint of sewage treatment facilities, and reducing residual sewage by maintaining a low sludge load Mud volume. Mainly use membrane separation equipment to intercept activated sludge and macromolecular organic matter in water. The concentration of activated sludge (MLSS) in the membrane bioreactor system can be increased to 8000~10,000mg/L or even higher; the sludge age (SRT) can be extended to more than 30 days. Due to its effective retention, the membrane bioreactor can retain microorganisms with a long generation cycle, and can achieve deep purification of sewage. At the same time, nitrifying bacteria can fully multiply in the system, and its nitrification effect is obvious, which provides the possibility for deep dephosphorization and denitrification. .
