Removal of Colour and COD from Reactive Green ? 19 Dyeing Wastewater using Ozone

Ozone is mainly used in the Advanced Oxidation Processes (AOP’s) refers to a set of chemical treatment procedures designed to remove organic and inorganic materials in dye industry wastewater by Ozonation process. Reactive Green ? 19 effluent is treated with Ozonation process. The operating parameters are Dye concentration (200, 300 & 400 ppm), time of ozone passing (20, 40 & 60 min.) & pH (4, 7 & 10). Experiments have to done for evaluated to find the optimum conditions for the Ozonation process. The contaminant materials are converted to a large extent into stable inorganic compounds such as water, carbon dioxide and salts, i.e. they undergo mineralization. The effect of Ozonation on the Decolourization, Degradation, and Mineralization of a dye, perform in a laboratory scale bubble column batch reactor. In Experiment Decolourization & Chemical Oxygen Demand (COD) will analyse. The effect of operational parameters on decolourization such as Ozone dosage and dye concentration in study.
