Abstract

The present invention relates to a method and a device for performing an ion-exchange process. The device according to the invention comprises: - a first electrode; - a second electrode separated from the first electrode; - a number of electrolyte compartments provided between the first and the second electrodes, wherein the electrolyte compartments are formed by a number of alternately provided cation exchange membranes and anions exchange membranes that are provided at a mutual distance, wherein the mutual distance is variable.
