Compact Membrane Bio Reactor is available with good nitrification that offers 95% NH4 removal and consumes less power during operation. The Membrane Bio Reactor ensures phosphorous removal by co-operation with iron or aluminium salts. The Membrane Bio Reactor operates under a slight suction [6-10 inches of Hg] drawing clean water to the inside of membrane filter, leaving suspended solids [MLSS] and colloidal particles in the process tank. Compact Membrane Bio Reactor can be used for both domestic and industrial wastewater treatment.
