Abstract

Abstract: Almost all human life requires water, one of which is washing clothes. However, city people tend to use laundry services. It is necessary to treat laundry wastewater because it contains parameters that can cause environmental pollution. A promising technique has been found to treat urban wastewater, especially laundry wastewater. An electrochemical method for water treatment is known as electrocoagulation, in which a solution of an active coagulant in the form of metal ions (aluminum or iron) is introduced into a solution. In electrocoagulation, the processes of adsorption, coagulation, precipitation, and flotation taking place. This research was conducted to determine the impact of current on electrocoagulation using Al-Al, Fe-Fe, Al-Fe, Fe-Al electrodes in reducing surfactant levels in laundry wastewater with variations in the voltage used were 20 V, 30 V, 40 V, and 60 V. The results showed that the electrocoagulation process could remove surfactants in laundry wastewater. A voltage of 30 volts with Al-Al electrode configuration was used for 30 minutes to obtain optimum conditions so that it will get a surfactant effluent concentration of 5.77 mg/L with a removal efficiency of 72.89%.
