Evaluating a Reverse Osmosis Membrane for 2-Chlorophrnol Removal from Aqueous Solutions

In this study performance of a commercial reverse osmosis membrane (TW30-1812-100) was evaluated for 2-chlorophenol separation from aqueous solution.Influence of operational conditions such as feed pressure, feed flow rate and concentration on 2-chlorophenol rejection was investigated. The results showed that at optimum condition, 200 mg/L, 408.1 kPa, pH =10 and 1.953×10-5 m3/s feed flow rate, 79% rejection was attainable. Results showed that the feed flow rate was the most effective parameter on the 2-chlorophenol rejection and rejection was increase with feed flow rate. The study of the influence of feed pressure showed a maximum critical pressure for rejection. However, the study of feed concentration on 2- chlorophenol rejection did not show a constant trend
