Present study is aimed to explore the pollution potential of automobile service station wastewater and to treat the same. The wastewater samples were collected from nearby automobile garage and the sample was characterized for various parameters like pH, Total solids, Total Suspended Solids, total dissolved solid as well as chemical oxygen demand (COD) etc. The characterization results revealed that COD were major pollution parameters of concern. This research presents a bench scale electrocoagulation methods applied for the treatment of automobile service station wastewater. Experiments were performed in batch mode in 2 L capacity cubical shape reactor. Four stainless steel plates were used as electrode for current study which was immersed in wastewater. Continuous stirring was performed for consistent of sample concentration throughout the experimental run by a magnetic stirrer. Direct current was applied to the electrodes by an external power supply. Different process parameters like pH and current were varied to evaluate the maximum efficiency conditions. Maximum COD removal of 80 percent was found at an optimal condition, current density of 19.74 A/m2 and pH 5.
