The membrane bioreactor (MBR) process is a modification of the conventional activated sludge process in which the membrane filtration unit.
The membrane bioreactor (MBR) process is a modification of the conventional activated sludge process in which the membrane filtration unit, instead of a secondary sedimentation tank, is used to separate the effluent from the activated sludge.
A submerged membrane bioreactor (SMBR) in which the membrane module is submerged inside the bioreactor tank and the permeate is suctioned directly by dead-end filtration. The membranes might be either submerged in the aeration tank or in the membrane tank according to the membrane make. In submerged configurations, the air is supplied for biological processes and membrane scouring. A SMBR is more often used to treat municipal wastewater, and can apply both hollow-fiber membranes (horizontal or vertical) and flat-plate membranes.
