Abstract

The invention relates to devices, systems, and methods for mixing one or more solutions to generate a recharge solution having specified concentrations of hydroxide and free chlorine for recharging and disinfecting zirconium oxide 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 the zirconium oxide.

First claim

1 . A system, comprising:
a sorbent recharger comprising at least one receiving compartment for a zirconium oxide sorbent module; an electrolysis system configured to generate at least a hydroxide solution, wherein the electrolysis system is fluidly connectable to the sorbent recharger; and a controller controlling at least one pump to deliver at least the hydroxide solution from the electrolysis system to the zirconium oxide sorbent module.

2 . The system of claim 1 , wherein the electrolysis system includes:
a reservoir configured to accommodate a salt solution; and an electrolytic cell configured to at least generate at least the hydroxide solution.

3 . The system of claim 2 , wherein the electrolytic cell includes an anode configured to oxidize the salt solution.

4 . The system of claim 2 , wherein the electrolytic cell includes a cathode configured to reduce water to form hydrogen and hydroxide ions.

5 . The system of claim 1 further comprising:
a water source fluidly connected to sorbent recharger and configured to dilute at least the hydroxide solution.

6 . The system of claim 5 , wherein the water source is downstream from the electrolysis system.

7 . The system of claim 1 further comprising:
a free chlorine source fluidly connected to the sorbent recharger.

8 . The system of claim 1 further comprising:
a mixer fluidly connected to the sorbent recharger and upstream of the zirconium oxide sorbent module.

9 . The system of claim 1 further comprising:
at least one sensor configured to measure a concentration of at least the hydroxide solution.

10 . The system of claim 9 , wherein the at least one sensor comprises a conductivity sensor.

11 . The system of claim 9 , wherein the at least one sensor comprises a pH sensor.

12 . A system, comprising:
a sorbent recharger comprising at least one receiving compartment for a zirconium oxide sorbent module; an electrolysis system comprising:
a power source;
an anode configured to oxidize a salt solution; and
a cathode configured to generate at least a hydroxide solution,
wherein the electrolysis system is fluidly connectable to the sorbent recharger; and a controller controlling at least one pump to introduce at least the hydroxide solution from the electrolysis system to the zirconium oxide sorbent module.

13 . The system of claim 12 , wherein the electrolysis system includes:
a reservoir configured to accommodate the salt solution.

14 . The system of claim 12 further comprising:
a water source fluidly connected to the sorbent recharger and configured to dilute at least the hydroxide solution.

15 . The system of claim 14 , wherein the water source is downstream from the electrolysis system.

16 . The system of claim 12 further comprising:
a free chlorine source fluidly connected to the sorbent recharger.

17 . The system of claim 12 further comprising:
a mixer fluidly connected to the sorbent recharger upstream of the zirconium oxide sorbent module.

18 . The system of claim 1 further comprising:
at least one sensor configured to measure a concentration of at least the hydroxide solution.

19 . The system of claim 18 , wherein the at least one sensor comprises a conductivity sensor.

20 . The system of claim 18 , wherein the at least one sensor comprises a pH sensor.
