Title
(EN) ELECTRODE SEPARATION TYPE WATER SOFTENING APPARATUS
Abstract
(EN)

Provided is a high efficiency electrode separation type water softening apparatus which softens a common water with a hard water characteristic in such a way to separate and remove a positive ion component using an ion exchange membrane, and converts most of a common water into a soft water in such a way to have a positive ion component be absorbed by a small amount of water flowing via the interior of an ion exchange membrane while extending a lot an exchange period of an ion exchange membrane, so it can be used for a long time. The electrode separate type water softening apparatus comprises a chamber which has a hollow inner space, a certain length and a positive electrode member, thus supplying an electric current (+) to its inner side; a negative electrode member 40 which is formed at the center of the chamber in a longitudinal direction of the chamber, with an electric current (−) being applied thereto; an ion exchange membrane which is disposed between the negative electrode member and the positive electrode member; a first input port and a second input port which separately input hard water into the inner side and the outer side of the ion exchange membrane, respectively; and a first discharge port which discharges the hard water inputted in response to the first input port and the second input port to the outside of the chamber and discharges a positive ion concentrated water C, and a second discharge port which discharges a soft water.
