Description

Capacitive deionization device This description relates to a capacitive deionization device. Various methods for water treatment devices that process raw water to produce purified water are currently being researched and developed. Among these, electro-deionization methods such as EDI (Electro Deionization), CEDI (Continuous Electro Deionization), and CDI (Capacitive Deionization) have recently been gaining attention. In particular, research on CDI (Capacitive Deionization), a capacitive deionization method, is currently being actively conducted. Capacitive deionization devices remove ions (pollutants) by utilizing the principle that ions are adsorbed and desorbed onto the surface of electrodes by electrical force. The operating modes of capacitive deionization devices include water purification and washing modes. In the purification mode, raw water (water to be deionized) passes between the electrodes while voltage is applied to each electrode. At this time, negative (-) ions move to the electrode to which a positive (+) voltage is applied and positive (+) ions move to the electrode to which a negative (-) voltage is applied, and ionic substances are adsorbed at each electrode. Through this purification mode, the capacitive deionization device can remove ionic substances from the raw water to produce purified water (produced water). If too much ionic material is adsorbed on the electrode surface, the efficiency of the water purification mode decreases. In the washing mode, no voltage may be applied to the electrodes, or a voltage opposite to that of the water purification mode may be applied to the electrodes. At this time, raw water is generally flowed between the electrodes to clean the electrode surfaces. When the washing mode is finished, purified water (produced water) can be produced again through the water purification mode. Generally, raw water containing a large amount of ionic substances is used in the cleaning mode. Since there is not a significant difference in concentration between the ions adsorbed on the electrode surface and the ions contained in the raw water, surface cleaning may not be performed properly or the cleaning time may be prolonged.
