Title:
ION EXCHANGE EQUIPMENT
Document Type and Number:
WIPO Patent Application WO/2021/166368
Kind Code:
A1
Abstract:
Provided is ion exchange equipment that provides an increased ion exchange capacity without requiring an expensive ion exchanger, and that enables an increase in the amount of impurity ions that are removed while decreasing the amount of permeation of a treatment material into a raw water part. The ion exchange equipment comprises: a raw water tank 1 accommodating a liquid to be treated, the liquid to be treated comprising a liquid containing impurity ions; a treatment tank 2 accommodating a treatment material, the treatment material containing exchange ions comprising ions exchangeable with the impurity ions; and an ion exchanger 3 allowing passage of the impurity ions from the raw water tank 1 to the treatment tank 2 and passage of the exchange ions from the treatment tank 2 to the raw water tank 1. The ion exchange equipment further comprises a voltage applying means E capable of applying a voltage to the ion exchanger 3.
