Desalination is crucial for freshwater access, but conventional methods like reverse osmosis (RO) suffer from limited water recovery, wasting billions of gallons annually. Brine disposal, often exceeding one-third of plant costs, presents environmental hazards through deep well injection and evaporation ponds. Salt-Free Electrodialysis Metathesis (EDM) offers a sustainable alternative. This electrically driven technology employs ion exchange membranes in a novel two-pass process, achieving over 97% water recovery from desalination brine. Unlike conventional EDM, it eliminates the need for added sodium chloride, significantly reducing costs and simplifying operations. By generating two highly soluble concentrate streams—calcium-rich and sulfate-rich—salt-free EDM mitigates the environmental impact of traditional brine disposal. This innovative approach addresses RO’s limitations, providing a cost-effective and environmentally sound solution for brackish water concentrate management. This presentation will detail system performance, including results from pilot demonstrations in Texas and New Mexico, ion transport, and energy consumption, showcasing its potential for sustainable desalination.
