Description

Water Treatment Apparatus The present disclosure relates to a water treatment device utilizing capacitive desalination technology. Desalination technology is a technology that is widely required across various industries, such as removing hardness components like calcium and magnesium from water in areas with high hardness content for drinking or boiler use, or for use as cooling water in power plants or factories. Capacitive deionization (CDI) technology is an example of deionization technology that removes ions by electrochemically adsorbing them onto electrodes with a high specific surface area. The capacitive desalination device comprises a single channel, electrodes with a high specific surface area on both sides of the channel to adsorb ions of the fluid flowing inside the channel, and an ion exchange membrane for the selective movement of specific ions. The capacitive desalination device is configured to move ions by an electric field generated perpendicular to the direction of fluid flow inside the channel. A capacitive desalination device may be included in a dishwasher or washing machine, etc. The capacitive desalination device may be installed in the water supply line to improve washing efficiency and prevent scale formation by softening the wash water to be used in the dishwasher or washing machine through a desalination process that removes ions in advance.
