De-fluoridation of Ground Water by Electro Coagulation Method

Abstract

Environmental issues have become serious social concerns of a global scale. Among these issues, the impact of water pollution is getting more serious because it is closely related to the health and lives of human beings. The removal or breakdown of organic compounds from wastewater is an important and integral part of any industrial chemical process. Treatment plants intended for the purification of any industrial wastewater utilize a combination of processing techniques such as Physical treatment, Physicochemical treatment and Biological treatment. Also, recent literature indicates the applicability of electrochemical process as an attractive alternative for application prior to biological methods. Electrochemical (EC) treatments such as electrocoagulation, electroflotation and electrochemical oxidation have been studied extensively because of their several advantages over a typical wastewater treatment plant. Electrochemical treatments generally have lower temperature requirements and require less space, and produce fewer byproducts or sludge.
