Abstrakt: The vegetable oil industry uses high amounts of water as a process and contains high concentrations of various pollutants and compounds resistant to biodegradation. In this study, the coagulation/flocculation process was applied to treat these wastewaters that have a negative effect on the receiving environment. In coagulation-flocculation experiments performed with Al2(SO4)3.18H2O, the highest COD (92%) and Oil-Grease (89%) removal efficiencies were obtained at a coagulant dose of 800 mg Al+3/L. In experiments conducted with FeCl3.6H2O coagulant, the highest COD (88%) and Oil-Grease (89%) removal efficiencies were obtained at a dose of 600 mg Fe+3/L coagulant. This study demonstrated the effective use of the coagulation/flocculation process in the treatment of vegetable oil industry wastewater containing high COD and Oil-Grease. [ABSTRACT FROM AUTHOR]
