Abstract
Water scarcity and water contamination are among the most challenging global issues today. Wastewater discharged into water bodies that are not appropriately managed causes a decrease in water quality, one of which is laundry wastewater which contains many hazardous materials resulting from the use of detergents and clothes deodorizers. This wastewater pollution management control uses a repeated filtration system with activated carbon as the main ingredient. This aims to determine the effectiveness of reducing the concentration of Chemical Oxygen Demand (COD), water turbidity, and odor level. Activated carbon effectively reduced the COD number from 964 Mg/L to 14 Mg/L. The turbidity level of water decreased from 302 to 2.29 on the NTU scale. This shows that a simple filtration system with activated carbon as the main ingredient for laundry wastewater treatment is very efficient in reducing COD levels, water turbidity levels, and odors from wastewater.
