Abstract
There are provided an apparatus for water treatment using capacitive deionization and a method for controlling the same. The apparatus for water treatment using capacitive deionization includes a first filter unit and a second filter unit allowing dissolved solids included in an introduced fluid to be adsorbed on electrodes to generate purified water when a water purification voltage is applied to the electrodes, and allowing the dissolved solids adsorbed on the electrodes to be desorbed to generate regenerated water when a regeneration voltage is applied to the electrodes, respectively, and a controller iteratively alternatively applying the water purification voltage and the regeneration voltage to the first filter unit and the second filter unit to generate purified water having a pre-set target total dissolved solids (TDS) value.
