Abstract: An ion exchange membrane is provided with a first cation exchange composition which has a cation exchange group and is formed in a sheet form; a first anion exchange composition which is disposed to be in contact with the first cation exchange composition, has an anion exchange group, and is formed in a sheet form. Furthermore, the ion exchange membrane is provided with a second cation exchange composition which has a cation exchange group, which is formed in a sheet form, and which is disposed to be opposed to the first cation exchange composition, and through which water permeates more easily than in the first cation exchange composition; and a second anion exchange composition which has an anion exchange group, which is formed in a sheet form, and which is disposed to be opposed to the first anion exchange composition, and through which water permeates more easily than in the first anion exchange composition.

Abstract: A water treatment apparatus of the present disclosure includes an electrochemical cell provided with an inlet and an outlet, a power supply that supplies electric power to electrodes, a first water flow path connected with the inlet, a second water flow path connected with the outlet, a soft water supply unit that feeds soft water to the inlet, and a flow adjustor that regulates a flow rate of water passing through the second water flow path. The water treatment apparatus further includes a controller that controls electric power supplied from the power supply to the electrodes, the flow rate of water passing through the second water flow path by use of the flow adjustor, and soft water fed to the inlet by use of the soft water supply unit when a process for regenerating the electrochemical cell is executed. As a result, the apparatus can reduce the hardness and electric conductivity of water fed into the electrochemical cell during regeneration of an ion exchange membrane and restrain scale formation.
