Treatment of traces of oil from electroplating industry wastewater by using membrane bioreactor

Membrane bioreactor (MBR) is a modification of an activated sludge process and is considered as a novel technology for treating wastewater. MBR process combines the activated sludge process with membrane filtration, which allows for a high effluent quality in terms of removal efficiency of oil and g...
