A capacitive deionization device comprising:
- at least one flow path configured to receive influent fluid;
- at least one pair of electrodes;
- at least one charge barrier disposed between the at least one flow path and a corresponding electrode of the at least one pair of electrodes;
- at least one electrolyte solution disposed between at least one electrode of the at least one pair of electrodes and a corresponding charge barrier of the at least one charge barrier;
- and
- at least one electrolyte compensation device in fluid communication with the at least one electrolyte solution, wherein the at least one electrolyte solution differs from the influent fluid, and wherein the at least one electrolyte compensation device comprises a compensation timing determination unit and a compensation unit.
A capacitive deionization device comprising:
- at least one flow path configured to receive influent fluid;
- at least one pair of a first electrode and a second electrode;
- at least one first charge barrier disposed between the at least one flow path and
- a corresponding first electrode of the at least one pair of a first electrode and a second electrode;
- at least one second charge barrier disposed between the at least one flow path and a corresponding second electrode of the at least one pair of a first electrode and a second electrode;
- at least one first electrolyte solution disposed between at least one first electrode of the at least one pair of a first electrode and a second electrode and a corresponding first charge barrier of the at least one first charge barrier;
- and
- at least one first electrolyte compensation device which compensates for at least one of a loss of ionic species from the at least one first electrolyte solution, a reduction in a total concentration of ionic species in the at least one first electrolyte solution and a reduction in a purity of the at least one first electrolyte solution, wherein the at least one first electrolyte solution differs from the influent fluid, and wherein the at least one first electrolyte compensation device further comprises:
- at least one ion transfer channel which directly connects the corresponding first electrolyte solution and the corresponding second electrolyte solution without passing through the at least one flow path, wherein the at least one flow path is insulated from the at least one first charge barrier and the at least one second charge barrier during a discharging process wherein the ionic species move through a corresponding ion transfer channel of the at least one ion transfer channel, instead of the at least one flow path, wherein the discharging process prevents a reduction in a total concentration of ionic species in at least one of a corresponding first electrolyte solution and a corresponding second electrolyte solution.
