Prophylactic aqua design and build the pertinent plant for the membrane bioreactor plant. MBR is the submerge membrane process in this membrane cassette is submerged into the biological tank or in a separate tank. Filtration takes place by applying vacuum by the pump on the membrane. We can use this membrane for the sewage and effluent treatment plants for a suitable application. Membrane bio-reactor eliminates the secondary clarifier thus saves upon civil cost and gets superior quality of the outlet water than a conventional system.
