Japanese Patent JP2019141803
Kind Code:
A
Abstract:
To provide a method for regenerating an ion exchange device capable of accurately regenerating an ion exchange resin.SOLUTION: A method for regenerating an ion exchange device including a step of passing a regeneration chemical liquid to an ion exchange device having an ion exchange resin layer, which detects a water quality, for example, an organic matter concentration, of a regeneration discharge liquid from the ion exchange device, and determines an end point of regeneration of the ion exchange device on the basis of the water quality. The ion exchange resin is preferably a weak basic anion exchange resin.SELECTED DRAWING: Figure 1
