  10. ED vs. RO: The Benefits Of Electrodialysis For Desalination
    8/11/2015

    There is no doubt that reverse osmosis (RO) currently reigns among desalination techniques, if your metric is total number of installations. But a new competitor has arisen, at least for particular applications. If you have brackish water in the 2,000 to 15,000 ppm range of total dissolved solids (TDS), you may want to consider electrodialysis (ED) over RO.
