Feasibility Study of Fenton Method for the Treatment of Dyeing and Printing Mill Wastewater

Textile industry is one of the most important and rapidly developing industrial sectors. It has a high importance in terms of its environmental impact, as it consumed high amount of processed water and produce highly polluted discharge water in large amount. Dying and printing mills comprises various operations include desizing, scouring, washing, finishing etc so they produces large amount of polluted effluent having high chemical Oxygen Demand. Advanced oxidation processes have emerged as a technology to accelerate the oxidation by generating hydroxyl radicals. Fenton treatment is one of the most attractive methods for the treatment of textile effluent. The use of Fenton’s reagent for the degradation of organic matter present in dying and printing mill’s effluent has been studied. The characteristics of the wastewater were checked. Experiments were carried out at a laboratory scale at different dosage to find out the optimum dosage of FeSO4 and H2O2.The optimum condition and efficiency were determined. Effect of the process parameter (dosage of FeSO4 and H2O2) has been checked. Highest efficiency of COD (74.24%) & BOD (72.41%) were achieved.
