<P>PROBLEM TO BE SOLVED: To provide an ion exchange apparatus that can reduce useless cleaning operation as much as possible to further reduce an operation cost while securing sanitary treatment water. <P>SOLUTION: The ion exchange apparatus includes: a circulating means 3 having: a water treatment mode for producing treatment water W2 by introducing raw water W1 into a pressure tank 2; a reproduction mode for reproducing an ion exchange resin bed 211 by introducing a regeneration liquid W4 into the pressure tank 2; a cleaning mode for cleaning the inside of the pressure tank 2 by introducing a cleaning liquid into the pressure tank 2; and a standby mode for not introducing a fluid into the pressure tank 2; a circulation detecting part 61 which can detect the presence of the circulation of the raw water W1 or the treatment water W2 into the pressure tank 2; a first timer means 52 for starting time measurement when the circulation detecting part 61 detects the absence of the circulation in a water treatment mode; and a circulation control means 51 for controlling the circulating means 3 to shift from the water treatment mode to the standby mode when reaches first predetermined time T3 by the first timer means 52. <P>COPYRIGHT: (C)2012,JPO&INPIT |
