Verfahren und Vorrichtung zum Entsalzen wäßriger Lösungen mittels Ionenaustauschermassen

摘要

Process for desalting aqueous solutions by means of granular cation and anion exchanger compositions layered in separate filter containers, and regeneration of these compositions, these compositions being exposed to charging/regeneration processes in a d.c. voltage field between two electrodes, a liquor taken off from a cathode chamber being used for the regeneration of the ion exchanger compositions and the regeneration of the exchanger compositions being carried out in counter-current to the treatment of the aqueous solution.
