Application of AOPs for the Treatment of Textile Industry Effluent

Advanced oxidation processes (AOPs) are now believed to be superior in treating industrial effluent, especially effluent of textile industry because of their several advantages over other treatment techniques, including conventional and biological treatment methods. In this study, an attempt has been made to assess the efficiency of AOPs, including Hydrogen Per Oxide alone, Fenton, Photo-Fenton, Solar Radiation assisted Photo-Fenton and Ozonation for the color and COD removal of textile effluent. AOPs are proven to be the efficient method for the treatment of textile effluent. The performance of Fenton process was slightly better. Ozonation was proved to be highly feasible and promising technique to decolorize and reduce COD from textile effluent but it is very costly. Photo-Fenton process via UV lamp considerably removed the color and COD but it is not economically viable. Photo-Fenton (sunlight) proved to be the most cost effective and efficient procedure for the color and COD removal among all AOP's, whereas Fenton process to be the second best option. So Solar assisted Photo-Fenton proved as the most energy and cost effective process among all AOPs.
