Abstract : This study is aimed to find treatability using Fenton Activated Carbon Catalytical Oxidation (FACCO)for treatment of Pesticide industry effluent. Pesticide effluent is not easily biodegradable so, FACCO as treatment is a good option to increase biodegradability of pesticide wastewater. The research was carried on the untreated waste effluent of Pesticide industry for the removal of COD. The optimum ratio of [H2O2] to [Fe2+] was 10:1 and 20:1 and the [COD] to [H2O2] ratio was 10:1, 6:1, 2:1 finalize at the pH value of 2.5 and 3.5. Lowering of pH was from 2.5 to 3.5 using sulphuric acid and sodium hydroxide, chemical dosed with hydrogen peroxide and Ferrous sulphate and ferric chloride (known as Fenton's reagent) was added. In this study, treatment of Pesticide effluent was carried out using combined system of Fenton oxidation process followed by adsorption on powder activated carbon (PAC). The effect of operating condition on Fenton oxidation processes such as hydrogen peroxide and iron concentration were investigated. About 60-65% COD reduction was obtained without any pre-treatment of the waste effluent at pH 2.5. The experimental results shows that maximum COD removal was obtain at 6:1 of COD:H2O2 ratio. The lad scale model suggested that the rate of reaction was highly affected by the concentration of hydrogen peroxide. So it is suitable for Advanced Oxidation process due to its non bio-degradable nature.
