Membrane Bioreactor membranes or MBR combination of membrane filtration and biological wastewater treatment. In this application, the membrane is immersed in the bioreactor, with the membrane isolating the solid waste and microorganisms, as well as, treating the water. The membranes provide a barrier effect so as not to allow passage of suspended solids, bacteria, and pathogens. Enhanced production of a quality effluent larger than the traditional means is achieved as a result of this process. MBR systems can be small in size and effective and hence can be installed in areas that are space-starved. They have gained currency in towns, small settlements, and organizations that need high-grade effluent that can be reused.
