1.4 Literature Review1.4.1 Introduction [1.3]The various treatment processes widely used for the treatment of wastewater in industries are filtration, air stripping, ion exchange, chemical precipitation, carbon adsorption. , ultrafiltration, reverse osmosis, electrodialysis and degassing. Beyond this technique based on advanced electrochemical technology is the process of electrocoagulation. Electrocoagulation, the passing of an electric current through water using electrodes, which is very effective in removing complex pollutants from water. Electrocoagulation techniques have been around for many years.1.4.2 Summary [1.4]Electrocoagulation technology is a technique almost similar to chemical coagulation. In chemical coagulation, pollutants present in waste or polluted water come together into a thick mass, allowing them to be easily removed. Unlike chemical coagulation, the significant advantages of CE
