In order to treat the wastewater containing organic compound, pre-treatment system connected with MSP(molecular separation process) was investigated. With the aim of selecting an optimum process of Fenton’s oxidation, removal efficiency of each process in the optimum reaction condition was recommended. The Fe/H₂O₂(ferric sulfate to hydrogen peroxide)reagent is referred to as the Fenton’s regent, which produces hydroxyl radicals by the interaction of Fe with H₂O₂. The powerful oxidizing ability and extreme kinetic reactively of the hydroxyl radical was well established. Increasing dosage of Fe/H₂O₂ increased removal efficiency as molar ratio of Fe/H₂O₂ between 0.2 and 2.5. Optimum dosage of molar ratio was 1. The removal efficiency for reaction condition was increased as pH decreased when the molar ratio of Fe/H₂O₂ was 1.7. Fenton’s oxidation was most efficient in the reaction time 35 min for complex wastewater. Also, coagulation aid experiments using kaolin resulted in 3% of kaolin dosage.
