The main objective of this study is aimed to investigate feasibility of the chemical and Aerobic biological process to treat oily wastewater from soya bean oil refinery. Effect of aeration and sludge concentrations are studied. The environmental impact of soybean oil refinery effluent cannot be over emphasized; hence the need for treatment measures to reduce these impacts before discharge. Therefore, this paper reviews the processing, purification of soya bean oil and the different methods of treatment applied to the soybean oil refinery effluent that is being generated. The basis of the proposed method for purification of wastewaters was a preliminary separation of clarified and neutralized wastewater by dint of concentrated lime, subsequently alum, Polyelectrolyte for water clarification and its additional neutralization was used.
