Abstract

An antimicrobial supply system employs a process water supply and incorporates a metallic ion supply connected to the process water supply to provide a high ion concentrate to an output. A dilution reservoir is connected to the metallic ion supply output and has an input from the process water supply. A pump is connected to an output of the reservoir. A manifold connected to the pump provides a dilute concentrate to at least one washing system. An electronics control module is connected to a first flow controller between the process water supply and the metallic ion supply and a second flow controller between the metallic ion supply and the reservoir for dilution control establishing a desired metallic ion concentration.

Claims

1. A method for infusing a metallic ion into a textile, comprising:

supplying, from a metallic ion supply, a high ion concentrate to a dilution reservoir connected to the metallic ion supply,

wherein supplying the high ion concentrate comprises;

receiving, by a metering pump, the high ion concentrate from a feed line of the metallic ion supply extending from a receiver of metallic ion supply, which engages a connection interface of a leak proof container, and

outputting, using the metering pump via a conduit of the metallic ion supply, a metered quantity of the high ion concentrate from the leak proof container of the metallic ion supply;

receiving, in the dilution reservoir, a process water supply;

mixing, in the dilution reservoir, the high ion concentrate and the process water supply to form a dilute concentrate; and

transferring the dilute concentrate from the dilution reservoir to at least one washing system including the textile.

2. The method of claim 1, wherein receiving the process water supply comprises operating, using an electronics control module, a first flow controller between the process water supply and the dilution reservoir, and

wherein supplying the high ion concentrate to the dilution reservoir comprises operating, using the electronics control module, a second flow controller between the metallic ion supply and the dilution reservoir.

3. The method of claim 2, wherein the high ion concentrate is a metallic silver solution.

4. The method of claim 2, further comprising detecting an identification element of the container recognizable by the electronics control module.

5. The method of claim 4, further comprising determining, by the electronics control module and based on the detected identification element, a presence of the container.

6. The method of claim 4, further comprising determining, by the electronics control module and based on the detected identification element, an origin of the high ion concentrate in the container and a usage history of the container.

7. The method of claim 1, further comprising mixing the high ion concentrate in the container.

8. The method of claim 7, wherein mixing the high ion concentrate in the container comprises operating a mixing driver in the receiver, which engages a mixing element in the container.

9. The method of claim 2, further comprising operating, using the electronic control module, a third flow controller to control a flow of the high ion concentrate between the dilution reservoir and a dosing pump, wherein the dosing pump is connected to an output of the dilution reservoir and a manifold for transferring the dilute concentrate from the dilution reservoir to the at least one washing system.

10. The method of claim 2, further comprising:

receiving, by the electronics control module, a first input from a dose level sensor;

receiving, by the electronics control module, a second input from a reserve level sensor;

receiving, by the electronics control module, a third input from a concentration sensor in the dilution reservoir;

determining, by the electronics control module based on the first input, the second input and the third input, an operating time period for providing a desired concentration of the metallic ion in the dilution reservoir; and

operating the metering pump for the determined operating time period to achieve the desired concentration of the metallic ion in the dilution reservoir.

11. The method of claim 10, further comprising receiving, from a user interface, user input indicating the desired concentration of the metallic ion,

wherein the first input and the second input each indicate a respective volume measurement, and

wherein determining the operating time period comprises determining the operating time period based on the user input and the respective volume measurements of the first input and the second input.

12. The method of claim 11, further comprising, based on the third input from the concentration sensor, operating a metering pump to supply the metered quantity of the high ion concentrate.

13. The method of claim 11, further comprising, based on the third input from the concentration sensor, operating the first flow controller to reduce the concentration of the metallic ion in the dilution reservoir.

14. A method for infusing a metallic ion into a textile, comprising:

providing, from a metallic ion supply to an output, a high ion concentrate of the metallic ion, wherein the metallic ion supply comprises;

a leak proof container for the high ion concentrate,

a metering pump receiving high ion concentrate from the leak proof container, and

a conduit providing the output of the metallic ion supply;

supplying, using the metering pump, the high ion concentrate from the output to a mixer;

operating, using an electronics control module, a flow controller to cause a process water supply to supply process water to the mixer;

mixing, using the mixer, the high ion concentrate and the process water to form a dilute concentrate; and

providing, via a manifold connected to the mixer, the dilute concentrate from the mixer to at least one washing system, wherein the at least one washing system includes the textile.

15. The method of claim 14, further comprising:

receiving the textile in a basin of the at least one washing system; and

agitating, in the basin, the textile while submerged in the dilute concentrate to infuse the textile with the metallic ion.

16. The method of claim 15, further comprising:

determining a mass of the textile in the basin; and

determining, based on the mass of the textile, a dosing rate for providing the dilute concentrate from the mixer to the at least one washing system.

17. The method of claim 16, further comprising determining, based on the mass of the textile, a dosing time period during which the dilute concentrate is provided from the mixer to the at least one washing system.

18. A method for infusing a silver ion into a textile, comprising:

simultaneously receiving, in a dilution reservoir, (i) a metered quantity of high ion concentrate of the silver ion from a silver ion supply and (ii) a metered quantity of water, wherein the silver ion supply comprises a leak proof container for storing the high ion concentrate and a conduit for providing the high ion concentrate to the dilution reservoir, wherein the metered quantity of high ion concentrate is received in the dilution reservoir from a metering pump;
