Title:
METHOD FOR OPERATING ION EXCHANGE SYSTEM
Document Type and Number:
Japanese Patent JP2023109499
Kind Code:
A
Abstract:
To provide a method for operating an ion exchange system capable of appropriately regenerating ion exchange towers so that regeneration timings of the respective ion exchange towers do not overlap.SOLUTION: There is provided a method for operating an ion exchange system including regenerating ion exchange towers sequentially so that while some ion exchange towers are being regenerated, other ion exchange towers are producing pure water, by differentiating a starting timing of raw water supply to each ion exchange tower and a stopping timing of pure water sampling. In a state where pure water is being produced in both the ion exchange towers with first and second regeneration orders, when a remaining water sampling time in the ion exchange tower with a second regeneration order reaches a required regeneration time of the ion exchange tower with the first regeneration order, regeneration of the ion exchange tower with the first regeneration order is started even if the ion exchange tower with the first regeneration order has not reached a scheduled water sampling amount.SELECTED DRAWING: Figure 1
