Abstract: This disclosure relates to the electrodialytic demineralization of water by passing soft water through a treating chamber defined by a pair of permselective membranes of which the one closer to the cathode of the cell is cationic permselective and the one closer to the anode is anionic permselective. The chamber is charged with an ion exchange material. The effluent from the treating chamber may be passed through a second like treating chamber. The ion exchange materials with which the cell or cells are charged may be cationic, anionic, both cationic and anionic, or cationic in one chamber and anionic in another chamber where more than one treating chamber is employed. The particular types of ion exchange materials selected will depend upon the flow pattern and arrangement of chambers in different electrodialytic cells embodying the invention.
