MBR-Membrane Bio-Reactor, This technology is a combination of a membrane process like microfiltration, nanofiltration, ultrafiltration with biological waste water treatment process i.e. ASP (ACTIVATED SLUDGE PROCESS). It is one of the most important innovation in waste water treatment as it overcome the drawbacks of the conventional ASP, including large space requirement for secondary clarifiers, liquidsolid separation issues, production of excess sludge, and limitations with removal of recalcitrant. Its claimed ability to hold and sustain mixed liquor suspended solids (MLSS) of three to four times than what is possible in the conventional aeration tanks which in turn offers minimization of the footprint of the treatment plant. Diffused aeration is of course needed.
