摘要：

Reverse Osmosis (RO) process is employed in several water desalination, wastewater treatment and food and beverage processing applications as an effective treatment method. In this paper, the efficiency of a proposed multi-stage retentate and permeate reprocessing design of RO process is investigated for the rejection of chlorophenol from wastewater via a detailed simulation. To achieve this aim, an earlier model developed by the authors is employed and validated against experimental data of chlorophenol removal from wastewater. This in turn aids to assess the interactions between the different parameters on the process performance. The simulation outputs confirm that the operating temperature has the biggest positive effect on the chlorophenol rejection. Also, the operating pressure has the biggest positive impact on recovery ratio. However, a minimum specific energy consumption is conducted at an optimum feed concentration. Moreover, the operating flow rate and pressure have a passive effect on the specific energy consumption. (C) 2019 Elsevier Ltd. All rights reserved.
