WATER REUSE: KEY TO INDUSTRIAL AIR EMISSION CONTROL
Abstract:This paper is a case study in the installation, startup and operation of a membrane bioreactor (MBR) designed to treat and recycle a blowdown stream from an air emission control device known as a wet electrostatic precipitator (WEP). The WEP system incorporates a recirculating wash water system that gradually collects solids and organics which must be removed from the wash water to maintain process efficiency and air permit compliance. The solids and organics are removed by an activated sludge biological treatment process followed by membrane filtration. The treated effluent is then returned back to the WEP wash water system for reuse.
