Membrane Bioreactor or MBR is an activated sludge process that utilizes a physical barrier, the membrane, to filter contaminants from effluent. Utilizing submerged membranes eliminates the need for secondary clarification and tertiary filtration. By decoupling the activated sludge process from the settling characteristics of suspended solids (Mixed Liquor Suspended Solids), the footprint of an effluent treatment process can be halved or even further lessened. In addition, an MBR is ideally suited for biological nutrient removal (BNR) applications as coagulated metal salts are easily filtered and captured phosphorous collected as waste activated sludge (WAS).


The key advantages of the system are it eliminates the process of secondary and tertiary filtration, reduces sludge production, is easy to retrofit and expand facilities, less footprint area required and is easy to operate. The effluent quality generated from MBR has BOD <5 mg/l, Turbidity <0.2NTU.
