Abstract

This paper reports preliminary stage from a study that combined magnetic field and electrocoagulation (EC) technology for removal of suspended particles in wastewater treatment. The experiments carried out in this work were setup into static methods. Batch experiments with two monopolar iron (Fe) plate anodes and cathodes were employed as electrodes. The effects of important process variables such as current density and operating time on the chemical oxygen demand (COD) and turbidity removal efficiencies were explored. Wastewater sample was made from powder milk with concentration 700 mg/L and acidic condition was employed (pH~3). DC current was verified at 0.5 – 0.8 A, and operating time at 30 – 50 minutes. The results show that the effluent wastewater was very clear and its quality exceeded the direct discharge standard. In addition, the experimental results also show that the electrocoagulation can neutralize wastewater pH.
