<P>PROBLEM TO BE SOLVED: To provide an ion exchange device capable of reducing a useless washing operation, to reduce an operation running cost. <P>SOLUTION: The ion exchange device includes a flow means 3 having a water treatment mode for producing treated water W2 by introducing raw water W1 into a pressure tank 2, a regeneration mode for regenerating an ion exchange resin bed 211 by introducing a regeneration liquid W4 into a pressure tank 2, a washing mode for washing an inside of the pressure tank 2 by introducing a washing liquid W1 into the pressure tank 2, and a standby mode introducing no fluid into the pressure tank 2, a flow detecting part 61 capable of detecting the presence of a flow of the washing liquid W1 into the pressure tank 2 in the washing mode, and a flow controller 51 for controlling the flow means 3, to be shifted from the washing mode to the standby mode, when the flow of the washing liquid W1 is not detected by the flow detecting part 61, in the washing mode. <P>COPYRIGHT: (C)2012,JPO&INPIT |
