Electro coagulation is based on the science of electrolysis. Electrolysis involves passing of electricity through the effluent. The electric current destabilizes the dissolved colloidal particles and alters the charge on suspended particles to coagulate the pollutants (Electro Coagulation). These coagulants trap the gaseous products of Electrolysis Reaction and start floating in the water (Electro Floatation). A combination of Electro Coagulation and Electro Floatation removes the pollutants from the Effluent.
