Membrane Bioreactors combine conventional biological Treatment process with membrane filtration to provide an advance level of organic and suspended solids removal. When designed accordingly, these systems can also provide an advances level of nutrient removal. In the MBR system, the membranes are submerged in an aerated biological reactor. The membranes have porosities ranging from 0.035 microns to 0.4 microns (depending on the manufacturer), which is considered between micro and ultra filtration. This level of filtration allows high quality effluent to be drawn through the membranes and eliminates the sedimentation and filtration processes typically used for wastewater treatment. Because the need for sedimentation is eliminated, the biological process can operate at a much higher mixed liquor concentration. This dramatically reduces the tank required and allows many existing plants to be upgrade without adding new tanks.
