Abstract: An ion exchange apparatus in which granular exchanger material is deposited to a level above a horizontal drainage for the regeneration medium solution of an ascending countercurrent regeneration process and considerably below an upper liquid connection. A timing generator that divides the regeneration phase into flow segments and rest segments is provided. To reduce the amount of regeneration medium required while changing only slightly the flow resistance and improving the exchanger efficiency, the concentration of the regeneration medium solution is increased to a value that without the timing generator leads to poor utilization of a given amount of regeneration medium. An additional layer of exchanger material excluded from the regeneration process is deposited to a level considerably above the drainage. An intermediate layer of exchanger material extends to a level considerably below the drainage, adjoins the additional layer, and can be mixed with the latter via a mixing device. As constituents of the mixing device, backwash nozzles are provided at the lower boundary of the intermediate layer. These backwash nozzles are distributed over a plurality of nozzle heads that are supplied via the drainage and spacers that extend downwardly from the drainage.

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.
