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 and a recirculation loop to the dilution reservoir for enhanced mixing of the dilute concentrate. 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

1-12. -12. (canceled)

13. An antimicrobial supply system comprising:

a process water supply;

a metallic ion supply comprising an output for providing a high metal ion concentrate;

a dilution reservoir connected to the metallic ion supply output and having an input from the process water supply;

a manifold connected to an output of the reservoir and at least one washing system, and,

an electronics control module connected to a first flow controller between the process water supply and the reservoir and a second flow controller between the metallic ion supply and the reservoir, wherein the controller controls a concentration of a dilute concentrate comprising the metal ion concentrate and process water in the dilution reservoir.

14. The antimicrobial supply system of claim 13, wherein the electronics control module is connected to a third flow controller that controls the flow of the dilute concentrate to the at least one wash system.

15. The antimicrobial supply system of claim 13, wherein the process water supply comprises a deionizer.

16. The antimicrobial supply system of claim 13, further comprising a probe in the dilution reservoir for measuring a concentration of metal ion in the dilute concentrate.

17. The antimicrobial supply system of claim 16, wherein the electronic control module receives input from the probe and controls said first and second flow controllers in response to the concentration of metal ion in the dilution reservoir.

15-1. The antimicrobial supply system of claim 13, wherein the process water supply comprises a reverse osmosis filter.
