Detergents are one of the most widely used chemicals in the daily life of humans. Their entry into the environment, especially water, can increase the COD of water and cause serious problems for living organisms. There are different methods to reduce COD. The electrocoagulation process as an electrochemical method is a suitable solution to reduce COD. In this study, the effect of electrocoagulation to reduce COD caused by laundry detergent has been surveyed. Process voltage, the number of electrodes, along with coagulation time as key parameters were investigated as influential parameters. The results showed that the 2-electrode mode reduced COD by 70% in 40 minutes at a voltage of 15 volts. This value was the most optimal energy consumption in terms of process time and the amount of reducing the pollution index.
