Membrane Bio-Reactor (MBR)

Membrane bio-reactor is the most efficient and advanced biological treatment available. Membrane biological reactor is the combination of two basic processes, biological degradation and membrane separation. These two processes are combined into a single process where microorganisms and suspended solids are separated from the treated water by membrane filtration unit. The membrane filtration is based on ultra or micro filtration, and it separates biomass from water. The MBR systems produce superior quality effluents, solids free and up to 99% reduction of organic pollution, in a compact and efficient system.


MBR combines activated sludge treatment with a membrane liquid-solid separation process. The membrane unit uses the low pressure micro-filtration or ultra-filtration membranes and eradicates the need for clarification and tertiary filtration. The membranes are plunged in the aeration tank, however some applications utilize a separate membrane tank. The key advantages of a membrane bio-reactor system is that it effectively overcomes the restrictions associated with ineffective settling of sludge in conventional activated sludge processes.



Advantages of Membrane Bio Reactors (MBR)
There are numerous advantages of membrane biological reactors over other treatment technologies. They are as follows:

• The quality of treated water is alike and doesn't vary.
• It provide enhanced quality of treated water.
• It confirm enhanced standards of hygiene.
• It provides safe rejection of biomass.
• Optimization and increasing of capacity for conventional plants
• Saving of the final sedimentation
• Higher efficiency due increasing concentration of biomass in the activated sludge tank.
