This research paper focuses on a design of a feasible and efficient technique for the reuse of industrial chemical wastewater. Combination techniques of the automatic restore filter (ARF) and reverse osmosis (RO) can be one of the possible solutions for treating industrial chemical wastewater. In this study, four types ( tin wastewater, Fine chemical industry wastewater, mixed chemical wastewater and Kumho chemical industry wastewater) of industrial chemical wastewater was evaluated using combined ARF and RO pilot plant, on the basis of COD, TN and TSS removal efficiency. Experiment was carried out using continuous flow operation system. Analyzing the all samples, we obtained the highest removal efficiency of COD, TN and TSS, 98.2%, 98.9% and 90.0%, respectively from tin wastewater. Also the removal efficiencies of Fine chemical industry wastewater, mixed chemical wastewater and Kumho chemical industry wastewater for COD, TN and TSS were 99.5%, 93.2%, 62.6%; 69.9%, 77.8%,95.0% and 99.8%, 86.9%, 99.0%, respectively. The results indicate that the combination of ARF and RO is a good technique for treating industrial chemical wastewater.
