Abstract
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.
