Abstract

Brackish water desalination process by electrodialysis, characterized in that in an electrodialysis cell formed by a series of compartments disposed on a dilution circuit, and others on a concentration circuit, and separated from each other by semi-permeable membranes, so that under the action of an electric field applied transversely with respect to said membranes, the anions and/or cations of the dilution circuit tend to pass to the concentration circuit through said membranes, the brackish water to be desalinated is circulated through the dilution circuit and seawater through the concentration circuit.
