In the present study, an effluent from textile industry is photo degradated under sunlight using TiO2 as photo catalyst. The process has been carried out at different pH, amount of catalyst and the doses of oxidant. Comparison of various advanced oxidation processes (AOP), (Sunlight, Sunlight/H2O2, Sunlight/H2O2/TiO2) for the chemical oxygen demand (COD) and color removal from the effluent are under taken. The degradation of the wastewater has been studied at pH 3, 7, 9, 11 and 0.3, 0.5, 0.7, 0.9 gm/100 ml of hydrogen peroxide doses. The effect of catalyst doses are also studied at 1, 3, 5 and 7 mg. The result showed that Chemical Oxygen Demand of the effluent substantially decreased. The solar photocatalytic method is effective for degradation of COD of the effluent.
