Review Paper on Electro Fenton Process for Waste Water Treatment

Abstract

Conventional processes for waste water treatments are inefficient for the remediation of waste water containing toxic and biorecalcitrant organic pollutants. Advanced Oxidation processes have been successfully applied to degrade toxic/Biorecalcitrant pollutants present in waste water. These methods are based on the generation of very powerful oxidizing agent such as hydroxyl radicals in solution able to destroy organic up to their mineralization. In recent years new AOPs based on the electrochemical technology are being developed. As an electrochemical advanced oxidation process (EAOP), electro Fenton process is powerful for degrading the toxic and biorecalcitrant organic pollutants. This paper reviews electro Fenton process including the mechanism, electrolytic bath, electrode materials, aeration, various operation parameters and advantages - disadvantage of the process.
