dc.description.abstractIn recent years, potable water scarcity has been observed worldwide because of the growing population and industrialization. One of the solutions that might be employed to address this situation is the treatment of contaminated water. This study aimed to evaluate the application of nanofiltration (NF) followed by electrodialysis reversal (EDR) on the concentrate stream of reverse osmosis (RO) operation for the advanced treatment of the membrane bioreactor (MBR) effluent in industrial wastewater. To investigate the impact of applied voltage (3, 5, 10, and 15 V) and the rate of flow (30, 40, and 50 L/h) on the EDR operation, an NF process (10 bar and at constant concentrate stream flow rate as 96 L/h) was employed as a pre-treatment before the EDR process for RO concentrate (TDS: 5520 mg/L) management. The flow rate showed almost no effect during the EDR process. Increasing the applied voltage led to a rapid rise in conductivity rejection, but it also caused a corresponding increase in specific power consumption (SPC). After considering the rejection performance, process time, and SPC, it became obvious that a 5 V of electrical potential is more appropriate than 3 V, 10 V, and 15 V. Application of EDR to NF permeate of the RO concentrate resulted in a conductivity rejection of 98.0% within 42 min when subjected to an electrical voltage of 5 V. The SPC was calculated to be 0.06 kWh/m3. To increase the amount of water recovered from the MBR effluent of wastewater and reduce the volume of brine discharged into surface water bodies, it has been demonstrated that NF integration with EDR was a feasible procedure for RO concentrate management. © 2024 FIMTEC & MPRL.en_US
