Recycling of Carwash Greywater Through Electrocoagulation Treatment
The need to recycle and reclaim large amounts of water wasted in different industries is becoming more critical by the day. The water needed at an automated carwash center can range between 150 to 600 L/car and is considered non-domestic greywater with high impurities due to oil and grease, high suspended solids, sand and dust, and a trace amount of other chemicals. Thus, the reuse of this greywater needs treatment. This study aims to assess and analyze the efficiency of the electrocoagulation process in removing turbidity, COD, and TOC from carwash effluent. The samples used in this paper were collected from a carwash station located in Sharjah, UAE. The study included nine different experimental runs of electrocoagulation, which was achieved by varying the pH and the time for the test sample. The electrodes were the same for all sets, and aluminum was used as anode and iron as the cathode. Results show that the percentage of turbidity removal in the electrocoagulation (EC) with an optimum pH of 7 was 97 at 30 minutes. The percentage of COD and TOC removal through EC with an optimum pH of 3 were 43% and 52% at 15 and 45 minutes, respectively. Also the operating cost of the electrocoagulation was found to be considerably low and it can be concluded that EC showed positive results with great potential in carwash greywater treatment and was proven effective in removing grease and oil.
