Abstract

A combined electrocoagulation (EC) technology and magnetic treatment was designed to enhance suspended particles removal from wastewater. This paper reports preliminary stage from a study that combined magnetic field and EC technology for removal of suspended particles in wastewater treatment. The experiments carried out in this work were setup into static methods. 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. In the batch experiments, two monopolar iron (Fe) plate anodes and cathodes were employed as electrodes. DC current was varified at 0.5 – 0.8 A, and operating time at 30 – 50 minutes. Three permanent magnets with different strengths were used in this experiment, namely NdFeB of 0.55T, SmCo of 0.16T and AlNiCo of 0.08T. The results show that using combined magnet and EC process obtain result better than without magnet.
