Electro Coagulation Reactor (ECR):Most of the contaminants are charged by DC electrical current and the contaminants are destabilized compressing the double layer and helps particles to come together. In the process of electrolysis, the ions in the water are precipitated and are coagulating. These coagulants and flocculants remove even colloidal particles by compellation improving the quality of treatment.

 Electro Floatation:Operating the system at the proper voltage and current imparts flotation energy to the coagulated particles through anode and micro gas bubbles released by cathode, in the process metal ions adhere to the pollutants, increase their size, gas micro structure help them to float on the surface and settled in the bottom of settling tank.
