Treatment process:
MBR (membrane bioreactor) is a combined process that combines biological treatment with membrane separation. A hollow fiber membrane assembly is placed in the bioreactor. The filtration hollow fiber membrane is an ultrafiltration membrane (UF) with a pore size range of 0.04μm, which is mainly used to intercept suspended liquids and organic matter. Its characteristics can maintain a certain concentration of microorganisms in the bioreactor and purify sewage.

MBR integrated equipment uses membrane bioreactor (MBR) for sewage treatment and reuse. It has all the advantages of membrane bioreactor: good effluent quality, low operating cost, strong system impact resistance, small amount of sludge, high degree of automation, etc. In addition, as an integrated equipment, it has a small footprint and is easy to integrate. It can be used as a small sewage reuse equipment or as a core treatment unit of a larger sewage treatment plant (station). It is one of the hot spots in the current sewage treatment research field and has broad application prospects.

Working principle:
Membrane bioreactor (MBR) process is a new wastewater treatment technology that organically combines membrane separation technology with biotechnology. It uses membrane separation equipment to intercept the activated sludge and macromolecular organic matter in the biochemical reaction tank, eliminating the need for a secondary sedimentation tank. The concentration of activated sludge is greatly increased, the hydraulic retention time (HRT) and the sludge retention time (SRT) can be controlled separately, and the refractory substances continue to react and degrade in the reactor.

Therefore, the membrane bioreactor (MBR) process greatly enhances the function of the bioreactor through membrane separation technology. Compared with traditional biological treatment methods, it is one of the most promising new technologies for wastewater treatment.
