Abstract:
Time until a conductivity meter is ready to measure a conductivity after an electric decationizing apparatus starts is shortened.
Water to be treated that contains cations and anions is supplied to the electric decationizing apparatus while applying a first voltage to the electric decationizing apparatus, and decationized water is generated. Next, the decationized water that is generated by the electric decationizing apparatus is supplied to the conductivity meter in order to measure conductivity of the decationized water. Before the first voltage is applied to the electric decationizing apparatus and before the conductivity meter begins measuring the conductivity of the decationized water, a second voltage that is lower than the first voltage is applied to the electric decationizing apparatus in a state in which the electric decationizing apparatus is charged with water to be treated.
