Photocatalytic Degradation of Real Textile Industrial Effluent under UV Light Catalyzed by Metal Oxide Nanoparticles

The domestic use and industrial activity, especially in developing countries, produce large amount of wastewater. This wastewater when disposed into natural channels may lead to high pollution risk. There are different methods for wastewater treatment one of them is Advanced Oxidation Processes (AOPs), still it has some limitations. The present work has been concentrated on the degradation of real textile industrial effluent named as Efluent1. The said Effluent1 was collected from textile industry from Echalkaranji; Maharashtra state was subjected to photocatalytic treatment using photocatalyst such as Degussa P-25 TiO 2 . Efluent1 was analyzed before and after the treatment for their physiochemical parameters like color, COD, TOC and presence of inorganic ions. Throughout the study it was observed that Degussa P-25 TiO 2 effectively brought out the degradation of Effluent. Addition of optimum amount of H 2 O 2 to the heterogeneous photocatalytic treatment was found to enhance the degradation of real textile effluents to a large extent. Hence, the photocatalytic degradation was found to be fruitful treatment for degradation of real textile industrial effluent as well as by adding oxidant the photocatalytic degradation has been enhanced.
