Electrochemical coagulation (ECC) technology has a long history and is still a very active location for research until today. The environmental sector showing large interest in ECC because of increasing pollution in different types of industrial effluent. It also contributions to the electrode material, operating condition, and reactor design. The electrocoagulation applications, advantages, and disadvantages discussed here. The goal is to form flocks of metal hydroxides among the effluent to be cleansed by electro-dissolution of soluble anodes. ECC was found to be capable of removing COD & Color from the affluent & it was found that the totally different electrode has different effectiveness in removing COD & Color, depends on the type of electrode. Finally, electrocoagulation can be the good option for the treatment of wastewater from various industries.
