Abstract
An electrodeionization apparatus includes an anode; a cathode; cation-exchange membranes and anion-exchange membranes alternately arranged between the anode and the cathode; desalting compartments and concentrating compartments arranged alternately to be located between the cation-exchange membrane and the anion-exchange membrane; and partition members situated in the respective desalting compartments to form cells therein. The partition member has inclined portions inclined obliquely relative to a longitudinal direction of the desalting compartment to define the cells laterally and vertically. Thus, one cell faces obliquely at least one of the cells adjacent thereto to allow water to flow obliquely between the one cell and the at least one of the cells. An ion exchanger is filled in the respective cells. The ion exchanger do not pass through the partition member.
