Title:
WATER TREATMENT APPARATUS
Document Type and Number:
Japanese Patent JP2023110716
Kind Code:
A
Abstract:
To provide a water treatment apparatus capable of stably giving water solubility to a hardly soluble salt solid at high efficiency with low cost.SOLUTION: The water treatment apparatus which is composed of an ion exchanger for ion exchange of any of constituent ions of a hardly soluble salt-containing aqueous solution, and adsorbs any of the constituent ions to the ion exchanger so as to elute the adsorbed constituent ions from the ion exchanger, includes: accommodation means for accommodating the ion exchanger; supply means for supplying a predetermined aqueous solution to the accommodation means; control means for variably controlling a channel length of an aqueous solution circulating in the accommodation means so that the length in the elution of the constituent ions from the ion exchanger is longer than that in the adsorption of the constituent ions to the ion exchanger; and extraction means for selectively extracting the aqueous solution where any of the constituent ions derived from the hardly soluble salt is dissolved by the control of the control means.SELECTED DRAWING: Figure 1
