Removal of Methylene Blue (MB) dye from synthetic wastewater using UV/H2O2 advanced oxidation process

Introduction: Advanced oxidation process is one of the most important techniques for the elimination of the wide ranges of organic pollutants from industrial wastewater with high efficiency. This research investigated Methylene Blue (MB) decolorization from synthetic wastewater using H2O2/UV as an advanced oxidation processes.Methods: Photo oxidation decolorization was conducted in a batch reactor with a shaking mode. Several arranges of the 8-watt UVC lamps were used for the process induction and the effects of operational variables including UV irradia-tion intensity, reaction time, initial concentrations of MB and H2O2were examined.Results: The results of this research show that the efficiency of process using H2O2/UV increased with increasing the UV irradiation intensity and H2O2 concentration. The best results for the removal of 3, 5 and 10 mg/l MB was per-formed with 1 Mmol of H2O2, 2400 μW/cm2 UV-C irradiation time within 3.5, 4.5 and 10.5 minutes of reaction time.Conclusion: Advanced oxidation processes using H2O2 and UVC irradiation can be used for MB decolorization which can be considered for the treatment of colored wastewaters including textile industries effluents
