Abstract

A device for treating water by a CDI method, according to the present invention, comprises: a filter means including first and second filter units having a water-purifying mode of discharging purified water by purifying raw water and a regeneration mode of regenerating an electrode according to the CDI method; and a control means for controlling the filter means. Here, if any one of the first and second filter units performs the water-purifying mode for a first time, the other one performs the reproduction mode for a second time. In addition, the control means determines the first time or the second time on the basis of the water-purifying performance of the first filter unit and / or the second filter unit.

Description

technical field [0001] The present invention relates to an apparatus for treating water by a CDI method, and more particularly, to an apparatus for treating water by a CDI method capable of effectively controlling water purification of a filter portion based on evaluation of the water purification performance of the filter portion Performance is constant in most cases. Background technique [0002] Currently, there are disclosed various devices for treating water, such as water purifiers, which process raw water to produce purified water. Recently, however, devices that treat water by a method of electrodeionization (EDI) such as electrodeionization (EDI), continuous electrodeionization (CEDI), and capacitive deionization (CDI) have become mainstream. Among them, the most popular are devices that treat water by the CDI method. [0003] The CDI method refers to a method of removing ions (pollutants) using the principle of adsorbing and releasing ions on an electrode surface...
