Membrane bioreactor (MBR) process is a new wastewater treatment technology that organically combines membrane separation technology and biotechnology. It utilizes membrane separation equipment
The activated sludge and macromolecular organic matter in the biochemical reactor are retained, and the secondary sedimentation tank is eliminated. The concentration of activated sludge is therefore greatly increased, and the hydraulic residence time (HRT) and sludge residence time (SRT) can be controlled separately, while the difficult-to-degrade substances are continuously reacted and degraded in the reactor.
Therefore, the membrane bioreactor (MBR) process greatly enhances the function of the bioreactor through membrane separation technology. Compared with the traditional biological treatment methods, it is one of the most promising new technologies for wastewater treatment.
