摘 要:Two-thirds of the world’s population has limited access to potable *** we continue to use up our freshwater resources,new and improved techniques for potable water production are ***,we present a general concept called“salinity exchangethat transfers salts from seawater or brackish water to treated wastewater until their salinity values approximately switch,thus producing wastewater with an increased salinity for discharge and desalinated seawater as the potable water *** have demonstrated this process using *** exchange has been successfully achieved between influents of different salinities under various operating ***-scale salinity exchange electrodialysis(SEE)systems can produce high-quality desalinated water at~1 mL/min with an energy consumption less than 1 kWh/*** has also been operated using real water,and the challenges of its implementation at a larger scale are evaluated.
