Abstract: An inexpensive ion-exchange apparatus with an increased ion-exchange capacity has a raw-water tank (1), a treatment tank (2) and an ion exchanger (3). The raw-water tank (1) contains a to be treated liquid. The liquid contains impurity ions. The treatment tank (2) contains a treatment material that contains exchange ions exchangeable with the impurity ions. The ion exchanger (3) enables 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 treatment material in the treatment tank (2) has a higher molarity than the to be treated liquid in the raw-water tank 1.

Abstract: An ion-exchange apparatus has a raw-water tank 1, a treatment tank 2, an ion exchanger 3 and a voltage applying device E. The raw-water tank 1 contains a to be treated liquid that has 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 voltage-applying device E applies a voltage to the ion exchanger 3.
