MBR membrane bioreactor

First, the device overview

MBR membrane bioreactor (Membrane bioreactor, MBR) is a membrane separation technology and bioreactors biodegradation set in one of the bioreactor system. It submerged membrane module to replace the traditional activated sludge in the secondary settling tank to achieve mud separation. The system has the processing capability, high solid-liquid separation efficiency, good water quality, small footprint, simple operation and management and so on.

Since the filtration membrane, microorganisms are completely trapped in the bioreactor, realized hydraulic retention time and active sludge age of complete separation, eliminating the traditional activated sludge bulking. MBR has high efficiency, strong nitration, water quality and stability, low sludge production equipment, compact, simple operation, removal of contaminants. After anoxic denitrification wastewater after nitrogen into the membrane bioreactor. Into the membrane pool of sewage by denitrification bacteria achieve nitrification denitrification, aerobic microorganisms while breathing through endogenous oxidative decomposition of organic matter and to reduce COD purposes. MBR submerged flat membrane device installed in the MBR tank mixture of mud and water filtration treatment, further removal of SS, oil, such as E. coli.

Membrane bioreactor stable, long wash cycle, producing low energy consumption, without adding coagulant, coagulant agent chemicals, reduce operating costs. MBR tanks sludge concentration, good impact resistance, small footprint, water quality is good.

Third, the principle

Membrane bioreactor (MBR) technology is a new wastewater treatment technology of membrane separation technology and biotechnology organic combination. It uses membrane separation device activated sludge biochemical pool and macromolecular organic matter trapped live, eliminating the need for secondary settling tanks. Thus greatly improving the activated sludge concentration, hydraulic retention time (HRT) and sludge retention time (SRT) can be controlled separately, and refractory material continuously in a reaction vessel, degradation.

Thus, membrane bioreactor (MBR) process by membrane separation technology has greatly strengthened the bioreactor function. Compared with conventional biological treatment, it is one of the most promising new wastewater treatment technology.
