The paper presents the results of experimental investigations of wastewater treatment by electrocoagulation (EC) technique. A combined magnet and electrocoagulation (EC) technology was designed to increase settling velocity and to enhance turbidity removal efficiencies from wastewater to a value more than 95%. The static method treatment consisted of an EC and magnetic field batch reactor with two parallel iron (Fe) plates were performed. 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. Wastewater sample was made from milk powder with initial COD of 1140 mg/L and turbidity of 491 NTU. DC current was varied at 0.5 – 0.8 A, and operating time of between 30 – 50 minutes. The results show that the process obtain better result than without magnet. Also, during the magnetic field and EC process at the operating time, the COD decrease by more than 65 %.
