Summary: | PROBLEM TO BE SOLVED: To provide an operation method for an ion exchange device which can prevent deterioration of water quality due to elution of organic substances and the like from a new ion exchange resin. SOLUTION: In the operation method for an ion exchange device having a first to n-th (n is an integer of 4 or larger) ion exchangers where, after water is passed through the first to n-th ion exchangers in this order, the first ion exchanger is subjected to maintenance and then water supply order is changed to restart water supply, the water supply order after the restart of the water supply is set so that the n-1-th ion exchanger, which has been the second from the tail end, is the tail end, the first ion exchanger subjected to the maintenance is the second from the tail end, and other ion exchangers are in the ascending order of their orders till then.
