Perspective of MBR Membrane Biological Reactor Systems (Membrane Bioreactors) for Wastewater Treatment

Membrane bioreactor systems can actually provide an affordable, simple-to-use solution to new or existing facilities facing environmental, regulatory and/or budgetary challenges. In addition to high quality of effluent, Membrane Bioreactor (MBR) technology has proven to offer great advantages: MBR technology drastically reduces system footprint requirements; MBR technology allows increasing plant capacity for existing infrastructures with minimal changes, while maintaining the existing facility operational if required, and driving down total installed costs. A Membrane Bioreactor (MBR) system is a biological process that combines a suspended growth activated sludge system utilizing low pressure membrane filtration for solid?liquid separation, typically ultrafiltration or microfiltration submerged membranes. Membranes are housed in modules that are assembled into cassettes and installed in a tank (called an MBR). Air is introduced through integral diffusers which provide scouring of the membrane surface during filtration, mixes the tank and also provides oxygen to the biological process.
