Abstract

A capacitive deionization (CDI) reactor for a CDI system including at least two electrodes formed with porous material and a plurality of conductive elements. The plurality of conductive elements in each electrode may be separate from each other. By incorporating a plurality of conductive elements in the electrodes, a CDI reactor according to one embodiment may enable substantially uniform charge distribution throughout the electrodes, irrespective of the size and shape of the electrodes. A method according to one embodiment may include regenerating the CDI system by successively reversing a polarity of voltage applied to electrodes of a CDI reactor, and reducing a magnitude of the applied voltage over time.
