Electrocoagulation is the process of removing suspended, dissolved, heavy metals, organic and emulsified pollutants by
applying direct current to electrodes for dissolution. The electrocoagulation process is widely used in various industrial water
treatment plants due to its low cost material and process design. In this frame, the paper presents a general review of EC
technologies employed for various samples of wastewater like dye mixed synthetic wastewater, sewer wastewater, and dairy
wastewater using different power supply models of EC having PV model and DC power supply.
