Innovative, cheap and effective methods of purifying and cleaning wastewater before discharging into any other water systems are needed. A combined magnet and electrocoagulation technology was designed to remove suspended solid from wastewater. Magnetic and EC treatments for water and wastewater attract a special attention due to their safety, ecological purity, environmental friendly and simplicity. This study is to investigate the effect of magnetic and electrocoagulation process. Wastewater sample was made from milk with concentration 700 mg/L, treated by using acetic acid (vinegar) as pH adjusment and electrolyte. This model will identify effect magnetic field or electrocoagulation on sedimentation or settling process of suspended solid in wastewater. The results suggest that using a combined magnet plus EC process obtain result better than without magnet.
Keywords : wastewater, megnetic fields, electrocoagulation, suspended solid.
