Patent ID: 7138042

Claim:
A capacitive deionization-regeneration system comprising in combination: (1) a battery of at least four electrochemical cells, each cell comprising at least one pair of adjacent electrodes including an electrosorptive medium having a high specific surface area and sorption capacity, formed on one or more surfaces of said electrodes; each pair of said adjacent electrodes including at least one aperture; and each pair of said adjacent electrodes forming an open channel, said open channel adapted to fluidly communicate with a subsequent open channel via said aperture to allow a fluid to flow across said electrosorptive medium and through the battery in a serpentine path, (2) an electrical circuit adapted for controlling the continuous deionization and regeneration operation of said battery of cells, said electrical circuit adapted for switching the polarity of each pair of said electrodes during each deionization cycle of each of said cells; and (3) a fluid circuit adapted for regulating the flow of a fluid through each of said cells under the control of said electrical circuit, in order to maintain a continuous deionization and regeneration operation of said battery of cells including a continuous output of deionized fluid from said system.
