Industrial wastewater comes textile, leather, food processing, dyeing, cosmetics, paper and paint manufacturing industries are important sources of dye pollution. Many dyes and their breakup products can be toxic to living organisms. Therefore, it is recommended to remove the wastewater containing dye with advanced treatment processes. In this study, the removal of cationic dye (methylene blue) with advanced oxidation processes by photocatalytic treatment was studied. TiO2 and ZnO catalysts were used as catalysts. 100% removal was achieved with both catalysts. The effects of catalyst concentration and dye concentration parameters on process efficiency were investigated. Effect of the catalyst concentration (0.25 g/L - 1 g/L) and dye concentration (10, 25 and 50 mg/L) onto dye removal efficiency was investigated. In addition, COD removal with TiO2 catalyst was investigated under optimum conditions. TiO2 catalyst was found to be much faster oxidation than ZnO catalyst. Much faster adsorption With ZnO catalyst compare to TiO2 was observed.
