Abstract
This paper investigates the application of electrocoagulation (EC) and electroflotation (EF) in wastewater originating from mixed vegetable oil (hazelnut oil, sunflower oil, soybean oil, corn oil and canola oil) processing factory. EC has been in use for industrial and domestic wastewater treatment finding more applications using aluminum (Al), iron (Fe) or hybrid Al and Fe electrodes. EF is proved to be perform better than any other methods and effective in removing colloidal particles, oil and grease as well as organic wastewaters.
This study aims to determine the optimum operating conditions for the treatment of wastewaters of mixed vegetable oil plant effluents with high organic pollution load by electrocoagulation method. The effects of pH, conductivity, current density and operating time on the removal efficiency of chemical oxygen demand (COD), total nitrogen (TN), total phosphorus (TP) and turbidity have been explored. The results show that 87.32 % COD, 51 % TN and 88 % TP removal has been achieved with optimum pH of 7-8 with 3 minutes reaction time and optimum energy of 250 A.
