The present study investigated the reverse electrodialysis (RED) energy generation potential of treated wastewaters from Ataköy and Ambarlı wastewater treatment plant (WWTP) when discharged at the Marmara Sea. The good quality of the WWTP effluents and their suitable conductivity (around 1 mS.cm⁻¹) resulted in a power density around 0.5 W.m^-2 when they are operated together with the Marmara Sea in a lab-scale RED system. This led to the generation of an approximative daily gross energy of 18.6 MW h and 16 MW h with Ataköy and Ambarlı WWTP, respectively. Considering optimal RED conditions able to reach a power density of 2.5 W.m^-2, Ataköy WWTP can generate net energy of 39.9 MW h.day which represents 25.1 % of the total energy demand of the plant. Similarly, the Ambarlı WWTP can cover 25 % of the plant energy demand by generating daily net energy of 36.8 MW h. Improving the characteristics of the ions exchange membranes (IEMs) by introducing highly selective and cost-effective membranes is part of the necessary solution to increase the power output of the process.

本研究调查了来自Ataköy和Ambarlı废水处理厂（WWTP）的经处理废水在马尔马拉海排放后的反向电渗析（RED）能量产生潜力。WWTP废水的良好质量及其合适的电导率（约1 mS.cm ^-1）导致了它们在实验室规模的RED系统中与马尔马拉海一起运行时的功率密度约为0.5 Wm ^-2。这导致Ataköy和AmbarlıWWTP分别产生大约18.6 MW h和16 MW h的每日总发电量。考虑能够达到2.5 Wm ^-2功率密度的最佳RED条件，阿塔科伊污水处理厂每天可产生39.9兆瓦时的净能源，占该厂总能源需求的25.1％。同样，Ambarlı污水处理厂每天可产生36.8 MWh的净能量，可满足工厂能源需求的25％。通过引入高度选择性和具有成本效益的膜来改善离子交换膜（IEM）的特性，是增加过程功率输出的必要解决方案的一部分。
