Electrocoagulation (EC) processes are a non-chemical, electrical means of removing suspended solids, colloidal material, and sparingly soluble salts as well as other dissolved solids from waters and wastewaters. EC has been successful in removing pesticides, radionuclides and is effective in removing bacteria, viruses, and biohazards, etc. Most systems use DC current where electrode plates are sacrificed (dissolved into solution) causing increased high metal concentrations that end up as oxide precipitates. Due to improved process design and equipment materials this electrical technology now offers advantages over chemical processes.
