Wastewater reclamation is gaining popularity worldwide as a means of conserving natural resources used for drinking water supply. 

The use of membrane bioreactor (MBR) technology, which combines conventional activated sludge treatment with low pressure membrane filtration, has been proven to be a feasible and efficient method of producing reclaimed water.  The membrane component of the MBR process eliminates the need for a clarifier and is performed using low-pressure membranes such as microfiltration (MF) or ultrafiltration (UF). 

MBR technology offers several advantages to conventional wastewater treatment including reduced footprint, consistent and superior effluent water quality and ease of operation. For many areas, it is necessary to further treat reclaimed wastewater to reduce its inherent salinity making it useable for irrigation and industrial use. 

The superior effluent water quality of the MBR process makes it suitable for further treatment by reverse osmosis (RO) membranes as a final polishing step in reducing the salinity of reclaimed water.
