摘要

<P>PROBLEM TO BE SOLVED: To provide an electrodialyser and a method for operating the same using no expensive electrode and capable of preventing the corrosion of an electrode throughout the duration of actual servicing. Ž<P>SOLUTION: The electrodialysis tank is partitioned off into a plurality of chambers arranged between electrodes with ion exchange membranes in between, and the chambers are supplied with each prescribed liquid in order to electrodialyze raw water.
