Abstract

Parallel modules for in-line recharging of sorbent materials using alternate duty cycles for a sorbent cartridge. The sorbent cartridge can have two or more modules contained therein having connectors connecting each of the modules. One or more of the modules can be reusable and the sorbent materials therein can be recharged.

Claims

1. A method of recharging a sorbent, comprising the steps of:

connecting at least a first module containing at least one sorbent material to a recharger;

wherein the recharger contains at least one fluid capable of recharging the at least one sorbent material; and

passing the at least one fluid capable of recharging the at least one sorbent material through the first module.

2. The method of claim 1, wherein the first module is fluidly connected to at least a second module containing at least a second sorbent material.

3. The method of claim 1, wherein the at least one sorbent material comprises zirconium phosphate, and wherein the at least one fluid contains sodium and hydrogen ions.

4. The method of claim 1, wherein the at least one sorbent material comprises zirconium oxide and wherein the at least one fluid contains sodium and hydrogen ions.

5. The method of claim 1, wherein the at least one sorbent material comprises activated carbon, and wherein the at least one fluid contains heated water.

6. The method of claim 1, wherein the at least one sorbent material comprises alumina and urease, and wherein the at least one fluid contains urease.

7. The method of claim 2, wherein the at least one sorbent material comprises either zirconium phosphate or zirconium oxide;

and wherein the second sorbent material comprises the other of zirconium phosphate or zirconium oxide.

8. The method of claim 2, wherein at least one of the at least one fluids capable of recharging the at least one sorbent material is not passed through the second module.

9. The method of claim 2, wherein the first module and second module are connected in parallel.

10. The method of claim 7, further comprising the step of connecting the second module to a recharger and passing the at least one fluid capable of recharging the second sorbent material through the second module.

11. A system, comprising:

at least a first sorbent module containing at least a first sorbent material;

the first sorbent module fluidly connectable to a recharger;

the recharger containing at least one fluid capable of recharging the at least one sorbent material.

12. The system of claim 11, further comprising at least a second module containing a second sorbent material;

the second module fluidly connected to a recharger and the first module.

13. The system of claim 12, further comprising at least a third module containing a third sorbent material;

the third module fluidly connectable to the second module.

14. The system of claim 11, wherein the first sorbent material comprises zirconium phosphate, and wherein the at least one fluid contains sodium and hydrogen ions.

15. The system of claim 11, wherein the first sorbent material comprises zirconium oxide and wherein the at least one fluid contains sodium and hydrogen ions.

16. The system of claim 11, wherein the first sorbent material comprises activated carbon, and wherein the at least one fluid contains heated water.

17. The system of claim 11, wherein the first sorbent material comprises alumina and urease, and wherein the at least one fluid contains urease.

18. The system of claim 12, wherein one of the first and second sorbent materials comprise zirconium phosphate and wherein the other one of the first and second sorbent materials comprise zirconium oxide.

19. The system of claim 11, wherein the first module is connectable to the recharger through at least one wash line.

20. The system of claim 12, wherein the first module and second module are connected in parallel.
