純水製造装置

Japanese Patent JP7193921

B2

To provide a pure water production apparatus capable of treating an ion exchanger with a more optimal regeneration frequency and amount of regenerant, reducing running costs, and suppressing deterioration of the quality of pure water.SOLUTION: The present invention provides a pure water production apparatus 1 that produces pure water using an ion exchange tower 2 that passes water to be treated through an ion exchanger to obtain treated water. The pure water production apparatus has: a conductivity meter 4 that is disposed at a preset position in the ion exchange tower 2 so as to be in contact with the ion exchanger 3 and includes at least one pair of electrodes to continuously measure a resin conductivity of the ion exchanger 3; and abnormality detection means 11 that detects a change in the measured value of the resin conductivity due to the adsorption or desorption of a plurality of ions passing through the ion exchange tower 2 to the ion exchanger 3, based on the measurement result of the conductivity meter 4 at the preset position, and generates an abnormality detection signal for warning of the occurrence of an abnormality when a change in the measured value of the resin conductivity due to ions that affect the quality of the treated water is detected.SELECTED DRAWING: Figure 1
