Treatment of metal finishing wastewater in sequencing batch process

Metal finishing wastewater contains heavy metals, acids, alkalis, detergents and toxic chemicals such as cyanide far above the Standard B limits of the Environmental Quality (Sewage and Industrial Effluent) Regulation 1979. A sequencing batch process utilising two-tank system was selected to trea...
