PROBLEM TO BE SOLVED: To provide an ion exchange apparatus capable of controlling ion removal, adjusting electric resistance as well as a pH value, and suppressing pressure failure to a comparatively low level. SOLUTION: The ion exchange apparatus 18 comprises at least a watercourse 38 extending from an inlet 32 to an outlet 34 to channel a fluid containing ions. At least a cartridge 36 holds ion exchange media 58 with the ion removal rate thereof variable according to the ion concentration of the fluid. COPYRIGHT: (C)2008,JPO&INPIT
