An electrodeionization apparatus comprising multiple anion exchange membranes 13 and cation exchange membranes 14 that are alternately arranged between a cathode 12 and an anode 11 to alternately form concentrating compartments 15 and desalting compartments 16 is described. The concentrating compartments 15 and the desalting compartments 16 are filled with ion exchangers, and the filling ratio of anion exchanger to cation exchanger of the ion exchanger in the concentrating compartments 15 is higher than that of the ion exchanger in the desalting compartments 16.
L'invention concerne un appareil de déionisation comprenant de multiples membranes échangeuses d'anions (13) et des membranes échangeuses de cations (14) qui sont disposées en alternance entre une cathode (12) et une anode (11), de manière que soient formés en alternance des compartiments de concentration (15) et des compartiments de désalage (16). Les compartiments de concentration (15) et les compartiments de désalage (16) sont remplis d'échangeurs d'ions, et le rapport de remplissage entre l'échangeur d'anions et l'échangeur de cations de l'échangeur d'ions dans les compartiments de concentration (15) est supérieur à celui de l'échangeur d'ions dans le compartiment de désalage (16).
