Treatment of Simulated Waste Water Containing Methyl Red by Advanced Oxidation Process
Journal Title: Journal of Advanced Chemical Engineering - Year 2017, Vol 7, Issue 2
Abstract
Advanced oxidation process is one of the promising technologies to eliminate the toxic pollutants, total organic contents etc. from waste water. Attempts are being made from previous few years on treatment of waste water using various advanced oxidation treatment methods like Fenton process. In Fenton process the reaction of FeSO4 and Fenton reagent H2O2 at low pH, involves the decomposition of Fenton reagent and results in Fe2+ generation, produce hydroxyl radicals which oxidize tough to decompose organics compounds due to its high oxidizing ability, in very short time. In this study, the application of Fenton process for the degradation of organic component from the water contaminated with methyl red an azo dye, has been inspected to present the assessment of Fenton process in waste water treatment. Concentration of Fenton reagent, ferrous sulphate and other process parameters like contact time and PH has been studied. H2SO4 and NaOH solution is used for pH adjustments. Different combination of experiments to check the COD removal, respect to the doses of H2O2 and FeSO4 has been performed. The optimum doses of which are 3.5 ml and 0.50 gm respectively, the best result (81.1% reduction) is obtained at pH of 3.0 ± 0.2, and reaction time of 30 min, and it is also proved that Fenton process is inefficient in alkaline and neutral medium.
