In present investigation, a combined methodology is followed called “peroxi-electrocoagulation method”. This combined process has several distinct advantages. Coagulants introduced without corresponding sulfate or chloride ions are more efficient at removing contaminants from water. By eliminating competing anions and using a highly pure coagulant source, lower metals residuals are obtained and less sludge is produced than when metal salts are utilized. A contaminant free ion source allows maximum removal of the various dissolved forms of pollutant that could be present and require treatment. Apart from the above the presence of OH radical has greater advantage for the removal process. It is reported [11] that as water-containing colloidal particulates, oils or other contaminants move through the applied electric field, there may be ionization, electrolysis, hydrolysis and free-radical formation which may alter the physical and chemical properties of water and contaminants [11]. As a result, the reactive and excited state causes contaminants to be released from water and destroyed or made less-soluble [12]. Further, when electrochemical reactors operate at a high cell potential/acidic pH and the anodic process occurs in the potential region of water discharge, hydroxyl radicals (OH) are generated [13], [14] and [15]. It is also confirmed [15] that ferrous ions act generated in electrocoagulation act as coagulation materials in the electrochemical treatment and catalytically create hydroxyl radicals to a small/larger extent depending upon the conditions.
