Industry represents an essential source of water pollution. Among the common industries which discharge wastewater is the textile industry. This industry causes environmental pollution including water pollution. To face this problem, recently, a new set of treatment technologies, called Advanced Oxidation Technologies (AOTs), has emerged which, does not only treat but also mineralize organic pollutants. Applying these AOTs in the treatment of the textile industry wastewater effluent is conducted in the present work. Sunlight is used as a source of UV light and the results are compared with those obtained when using an artificial source of UV light. A photo-chemical reactor is used to carry out the experiments. The concentration of the pollutants in the effluent subjected for treatment is followed along the treatment time. The kinetic constants were compared. Values of the kinetic constants of 0.0421, 0.031, 0.0132 and 0.0087 were obtained for photo-Fenton, UV/TiO2/H2O2., UV/H2O2 and UV/TiO2 processes, respectively. Rough cost estimation for different treatment systems clarified that the photo-Fenton’s reagent is far cheaper than other AOTs. Finally, the results obtained are used as a basis for suggesting an arrangement for a photo-catalytic treatment plant.
