In this work, various bonding techniques for the aluminum electrode were used to explore the electrocoagulation method for treating laundry wastewater. By combining the laundry water in specific ratios (1:1:1,5 ratio of the wastewater after prewash, main wash, and rinsing), the wastewater was characterized. Aluminum electrodes were employed as the anode and cathode, and purification was conducted using monopolar parallel (MP-P), monopolar series (MP-S), and bipolar parallel (BP-P) in various connection configurations. For each bonding form, the impacts of process variables like pH, current density, and time on COD, MBAS, and turbidity removal were examined. In the experiments, the maximum removal efficiencies for COD, MBAS, and turbidity, respectively, were obtained in the form of MP-P binding, at pH 5.5 for 15 minutes and at a current density of 5 mA/cm(2). The corresponding values were 80%, 97%, and 97%, respectively. The optimum removal conditions in the system examined with a monopolar parallel connection were pH 5.5, duration 15 minutes, current density 5 mA/cm(2), temperature 25 degrees C and stirring speed 200 rpm. The optimal removal efficiencies for MBAS, COD, and turbidity were determined to be 97%, 80%, and 96%, respectively.
