<P>PROBLEM TO BE SOLVED: To provide an upflow regeneration type ion exchange apparatus in which fluidization of an ion exchange resin is restrained without increasing the flow rate of pressing water when the ion exchange apparatus is in regeneration operation. <P>SOLUTION: The upflow regeneration type ion exchange apparatus 1 is provided with a resin housing part 2 packed with the ion exchange resin 5 and a regenerating liquid supply unit 4 for supplying a regenerating liquid to the resin housing part 2 when the ion exchange apparatus is in regeneration operation. The regenerating liquid supply unit 4 is provided with: a regenerating liquid warming means 23; a temperature detecting means 25 for detecting the ambient temperature of the regenerating liquid supply unit 4 or the temperature of the regenerating liquid; and a temperature controlling means 26 for starting the operation of the regenerating liquid warming means 23 when the value detected by the temperature detecting means 25 is equal to or lower than the first preset temperature and stopping the operation of the regenerating liquid warming means 23 when the value detected by the temperature detecting means 25 is equal to or higher than the second preset temperature. <P>COPYRIGHT: (C)2008,JPO&INPIT |
