Enhancing suspended solids remove from waswtewater using Fe electrodes

Abstract

This paper investigates the effect of electrocoagulation (EC) process on the removal of suspended solids (SS) from wastewater. In a batch electrochemical cell experimental set up, two monopolar iron (Fe) plate were used as electrodes (anodes and cathodes). Synthetic wastewater, made of milk powder with concentration of 700 mg/L, was treated using 1M HCl for pH adjustment before it was used as electrolyte. Preliminary results show that the EC process is able to enhance the removal of suspended solid, turbidity and carbon oxygen demand in wastewater. The removal rates of those elements were increase with treatment time.
