ABSTRACT:
After agriculture, textile and dyeing industry will be the second largest employment opportunity in India. It has its importance due to its environmental impacts because of the waste water produced with high chemical Oxygen Demand, turbidity. Treatment technologies generally used for degradation of dyeing effluent includes electro-oxidation, bio-treatment, photochemical, and membrane processes, Biodegradation, Coagulation–flocculation, adsorption on activated carbon, Ozone treatment. In this paper treatment of dyeing industry waste water through Fenton's reagent is investigated. The experimental results are assessed in terms of COD and color reductions in dyeing wastewater, to determine the efficiency of the Fenton's process. Operating variables of Fenton's treatment such as the pH, reaction time, concentration of H2O2 and FeSO4, initial concentration of wastewater were explored to determine their respective effects on the efficiency of the Fenton's oxidation of the dyeing industry wastewater. Optimum operating range for each of those variables was obtained through batch studies. The optimum pH was observed to be at 3 and optimum ratio of FeSO4 to H2O2 was 2:1. Fenton oxidation showed an efficiency of 72% in 2 h of reaction time, and it goes up to 75-78% in 6 h. Kinetics and thermodynamics studies on the Fenton oxidation of organics of dyeing industry waste water also performed.
