Recharge solution for zirconium phosphate
The invention relates to devices, systems, and methods for mixing one or more solutions to generate a recharge solution having specified concentrations of a sodium salt and acid for recharging and disinfecting zirconium phosphate in reusable sorbent modules. The devices, systems, and methods can generate a recharge solution by a sorbent recharger that is introduced through the sorbent module to recharge and to disinfect the zirconium phosphate.
1. A system, comprising:
a sorbent recharger having a recharging flow path comprising at least one receiving compartment for a zirconium phosphate sorbent module; the at least one receiving compartment comprising a zirconium phosphate module inlet and a zirconium phosphate module outlet;
at least one recharge solution source; the at least one recharge solution source comprising an acid source and a sodium source; and
a controller controlling at least one pump to introduce fluid from the at least one recharge solution source through the zirconium phosphate sorbent module.
2. The system of claim 1 , the at least one recharge solution source further comprising a base source.
3. The system of claim 1 , wherein the sodium source is selected from the group consisting of sodium chloride, sodium acetate, sodium phosphate, sodium citrate, sodium hydroxide, and combinations thereof, and the acid source is selected from the group consisting of acetic acid, phosphoric acid, sulfuric acid, citric acid, and combinations thereof.
4. The system of claim 1 , wherein the sodium source and acid source is selected from sodium diacetate, monosodium citrate, monosodium phosphate, sodium bisulfate, and combinations thereof.
5. The system of claim 1 , wherein the at least one recharge solution source comprises a source of solid sodium salt, solid acid, and/or solid sodium salt and solid acid.
6. The system of claim 3 , wherein the source of solid sodium salt, solid acid, and/or solid sodium salt and acid comprises a partitioned bag containing solid sodium salt, solid acid, and/or solid sodium salt and solid acid.
7. The system of claim 6 , wherein the partitioned bag containing solid sodium salt, solid acid, and/or solid sodium salt and solid acid comprises an inlet fluidly connectable to a water source and an outlet fluidly connectable to the recharging flow path.
8. The system of claim 1 , wherein the at least one recharge solution source comprises a saturated source of a sodium salt.
9. The system of claim 3 , wherein at least one recharge solution source comprises a saturated source of sodium acetate.
10. The system of claim 3 , wherein at least one recharge solution source comprises a liquid acid.
11. The system of claim 1 , further comprising a water source fluidly connected to the recharging flow path.
12. The system of claim 3 , wherein at least one recharge solution source comprises sodium hydroxide.
13. The system of claim 1 , further comprising a mixer fluidly connected to the recharging flow path.
14. The system of claim 1 , further comprising at least one sensor fluidly connected the recharging flow path.
15. The system of claim 1 , further comprising a second recharging flow path comprising a second receiving compartment for a zirconium oxide sorbent module; the second receiving compartment comprising a zirconium oxide module inlet and a zirconium oxide module outlet; and at least a second recharge solution source; the at least second recharge solution source containing at least a hydroxyl source and a free chlorine source.
16. The system of claim 14 , wherein the at least one sensor is a conductivity sensor.
