Patent ID: 7981268

Claim:
A capacitive deionization pumping system for treatment of a fluid containing ions, comprising: a feed flow channel of the fluid containing the ions; a concentrate flow channel; a first flow channel connecting said feed flow channel and said concentrate flow channel configured to fluidly communicate an oscillating flow between said feed flow channel and said concentrate flow channel; a second flow channel connecting said feed flow channel and said concentrate flow channel configured to fluidly communicate an oscillating flow between said feed flow channel and said concentrate flow channel; a first pair of conductive plates in said first flow channel adapted about said first flow channel; a second pair of conductive plates in said second flow channel adapted about said second flow channel; a clean fluid outlet connected to said feed flow channel, said first flow channel, and said second flow channel; a waste fluid outlet connected to said concentrate flow channel, said first flow channel, and said second flow channel; an electrical circuit electrically coupled to said first pair of conductive plates and to said second pair of conductive plates; a fluid circuit fluidly coupled to said feed flow channel and said concentrate fluid channel, and said first flow channel, and said second flow channel so as to produce said oscillating flow and flow of said feed flow channel to said clean fluid outlet and flow of said concentrate flow channel to said waste outlet; and a computer configured to control said electrical circuit and said fluid circuit so as to apply a periodic electric field to said first pair of conductive plates and said second pair of conductive plates in synchronization with said produced oscillating flow so as to facilitate a directed movement of the ions therethrough said predetermined flow channels from said feed flow channel to said concentrate flow channel through said first flow channel and said second flow channel wherein the ions are attracted by said periodic electric field applied to said first pair of conductive plates and said second pair of conductive plates.
