ELECTRODEIONIZATION APPARATUS

摘要

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).
