Treatment of Car Washing Unit Wastewater by Electrocoagulation

Abstract

Abstract
Enormous amount of water is being used to wash a car. With the increase in number of cars day-by-day, the quantity of water being used to wash cars is also increasing. Generally, effluent from car washing units is discharged into public sewers without treatment. In this study, the wastewater from a car washing unit was collected in a bulk quantity and characterized. It was treated with the electrocoagulation process with a lab scale setup using aluminium electrodes. Initial wastewater pH, interelectrode distance, conductivity, treatment time and voltage were optimized by calculating the percentage removal efficiency of turbidity and COD in each set of experiments. After the optimization of parameters, the characteristics of treated wastewater were calculated.

Keywords: Electrocoagulation, car wash effluent, COD removal, MBAS removal, turbidity removal
