Title:
ION-EXCHANGE DEVICE, COLUMN THEREFOR, AND WATER TREATMENT DEVICE
Document Type and Number:
WIPO Patent Application WO/2011/040278
Kind Code:
A1
Abstract:
Provided is an ion-exchange device including a column in which an anion-exchange resin and a cation-exchange resin are prevented, without fail, from being reversely regenerated. With the device, it is possible to produce high-quality deionized water even immediately after regeneration. Also provided is a column for the device. During regeneration, a valve (12) is closed and valves (7, 10) are opened, and a solution of an acid such as HCl is supplied through upper supply/discharge piping (3), while a solution of an alkali such as NaOH is supplied through third connecting piping (8). The acid solution flows through a water collection/distribution member (4), an inert resin (22), a cation-exchange resin (21), a water collection/distribution member (6), connecting piping (5), and the valve (7) in this order to regenerate the cation-exchange resin (21). The alkali solution flows through a water collection/distribution member (9), an inert resin (32), an anion-exchange resin (31), a water collection/distribution member (14), and lower supply/discharge piping (13) in this order to regenerate the anion-exchange resin (31).
