Abstract: Advanced oxidation process (AOP) is an efficient method to treat wastewater generated from pulp and paper industry. Hydroxyl radical (OH) is responsible for the degradation of organic pollutant generated by the reaction of iron ion and hydrogen peroxide in the Fenton process. In this study, real wastewater was taken from pulp and paper industry, India. The lignin is mainly responsible for high Chemical Oxygen Demand (COD) in pulp and paper wastewater. For the present investigation, three independent variables were chosen COD: H2O2, H2O2: Fe2+ and time. The maximum 94% COD removal was found at the optimized value of 0.165, 0.0165 and 115 for the COD:H2O2, H2O2:Fe2+ and time respectively. The response surface methodology (RSM) was applied to optimize the operational parameters.
