The improved electrically regenerable demineralizing apparatus uses ion exchangers that are produced by radiation-initiated graft polymerization and that are packed in the demineralizing compartment of an electrodialyzer. The apparatus may use a mosaic ion exchanger that consists of alternately arranged cation- and anion-exchange groups. Alternately, the apparatus may have an immobilized amino acid packed in the demineralizing compartment of an electrodialyzer. The apparatus maintains consistent water quality for a prolonged time, is capable of treating from small to large volumes of water and yet is easy to service and manage.
In an electrically regenerable demineralizing apparatus having a demineralizing compartment between two ion exchange membranes for removing ions from a liquid, and an ion exchange material contained in said demineralizing compartment, the improvement comprising:
The ion exchange fiber of claim 7, further comprising said ion exchange resin formed from fibers prepared by radiation-initiated graft polymerization in combination with an ion exchange resin formed by means other than radiation-initiated graft polymerization.
