TREATMENT OF SERVICE STATION WASTEWATER USING ELECTROCOAGULATION PROCESS

The various electrodes such as iron, aluminium, stainless steel and graphite are used in this study. Main objectives of the present paper is to evaluate the removal of COD, pH, TDS and oil and grease from the automobile wastewater by Electro coagulation using iron as Monopolar configuration at different voltages and electrolysis time. To study the effect of inter electrode spacing and effect of different initial pH for the removal of selected parameter at constant voltage for the iron electrode. The removal efficiency decreases with increase in electrode spacing as 71.2% of COD, 96.5% of TDS and 88.76% of oil and grease removal was achieved with iron electrode
