OPTIMIZATION OF SIMAFIX RED DYE DECOLORIZATION BY USING ADVANCED OXIDATION PROCESS: PHOTO-FENTON
Keywords:textile wastewater, optimization, photo-Fenton process, hydroxyl radicals.
This study investigated the Photo-Fenton process in textile wastewater treatment by using textile synthesis wastewater made of Symafix Red Dye solution. The aim of the study was to investegate the factors that influent to the photo-Fenton process such as contact time, pH, H2O2 and Fe2+conectrations, and UVexposure in order to research the optimum values of this process.Treatment of textile wastewater was carried out at ambient temperature in a batch reactor. As a result, the second-order is suitable for the reaction of removing color by using Photo –Fenton processes. The removal efficiencies decreased when we increased the concentration of Fe2+ from 7.162 mM to 14.162 mM. When we increased the H2O2 concentration from 0.037 mM to 0.11mM, the removal efficiencies slightly decreased. The optimum value of pH is pH = 3. At the optimum of pH value and minimum the concentration of Fe2+ and H2O2 the removal efficiency could reach up to 95.82 %.
