Abstract
An ion-exchange apparatus includes a raw-water tank 1, a treatment section, an ion exchanger and a hydrophilic layer. The raw-water section contains a liquid to be treated with impurity ions. The treatment tank 2 contains a treatment material with exchange ions exchangeable with the impurity ions. The ion exchanger 3 enables the passage of the impurity ions from the raw-water tank 1 to the treatment tank 2 and the passage of the exchange ions from the treatment tank 2 to the raw-water tank 1. The hydrophilic layer M, with a water contact angle of 30° or less, is disposed on at least a surface of the ion exchanger adjacent to the treatment tank 2.

An ion-exchange apparatus comprising:
- a raw-water section containing a to be treated liquid, the liquid includes a liquid that contains impurity ions;
- a treatment section containing a treatment material with exchange ions including ions exchangeable with the impurity ions;
- an ion exchanger enabling passage of the impurity ions from the raw-water section to the treatment section and passage of the exchange ions from the treatment section to the raw-water section;
- a hydrophilic layer, with a water contact angle of 30° or less, is disposed on at least a surface of the ion exchanger adjacent to the treatment section.
A method for producing an ion-exchange apparatus that includes a raw-water section containing a to be treated liquid, the liquid including a liquid that contains impurity ions:
- a treatment section containing a treatment material that has exchange ions including ions exchangeable with the impurity ions;
- an ion exchanger that enables passage of the impurity ions from the raw-water section to the treatment section and passage of the exchange ions from the treatment section to the raw-water section,
- the method comprising:
- forming a hydrophilic layer, with a water contact angle of 30° or less, on at least a surface of the ion exchanger adjacent to the treatment section.
