ABSTRACT:
An apparatus for desalting water by electrodialysis. The apparatus includes a circular cylindrical tank in which are provided a central electrode which extends along the axis of the tank, a coaxial electrode chamber which embeds the central electrode in electrolyte solution, a coaxial resin chamber which contains ion exchange resin, and a coaxial brine chamber. The separation of adjoining chambers is effected by respective membranes, which are permeable to either cations or anions. The brine chamber is disposed between the resin chamber and the electrode chamber which contains the central electrode. A further electrode chamber, which is designed for receiving another electrolyte solution, is disposed between the resin chamber and the wall of the tank. This further electrode chamber is hollow cylindrical.
