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 ### Claim 1 An antimicrobial supply system comprising: a metallic antimicrobial agent supply comprising a metallic antimicrobial agent concentrate supply and an output for the metallic antimicrobial agent concentrate; a dilution reservoir, wherein the dilution reservoir is a bulk reservoir, in fluid connection to the output of the metallic antimicrobial agent supply and having an input from a diluent supply, and wherein the dilution reservoir is configured to form a dilute concentrate from (i) diluent received from the diluent supply via the input of the dilution reservoir and (ii) the metallic antimicrobial agent concentrate received from the metallic antimicrobial agent supply via the output of the metallic antimicrobial agent supply; an output of the dilution reservoir coupled to at least one application system; and an electronics control module connected to (i) a first flow controller between the diluent supply and the dilution reservoir and (ii) a second flow controller between the metallic antimicrobial agent supply and the dilution reservoir, wherein the electronics control module is configured to: control, based on a predetermined metallic antimicrobial agent concentration in the dilute concentrate, the first flow controller and the second flow controller to achieve a desired metallic antimicrobial agent concentration of the dilute concentrate in the dilution reservoir. ### Claim 2 (depends on 1) The antimicrobial supply system of claim 1, further comprising: a concentration probe in the dilution reservoir and configured to measure a metallic antimicrobial agent concentration of the dilute concentrate in the dilution reservoir. ### Claim 3 (depends on 2) The antimicrobial supply system of claim 2, wherein the electronics control module is further configured to receive, from the concentration probe, an indication of the metallic antimicrobial agent concentration of the dilute concentrate in the dilution reservoir. ### Claim 4 (depends on 3) The antimicrobial supply system of claim 3, wherein the electronics control module is connected to a third flow controller that controls flow of the dilute concentrate to the at least one washing system. ### Claim 5 (depends on 2) The antimicrobial supply system of claim 2, further comprising a sensor in communication with the electronics control module, wherein the sensor comprises at least one of a temperature sensor, a pressure sensor, an air pressure sensor, or a flow sensor. ### Claim 6 (depends on 5) The antimicrobial supply system of claim 5, wherein the sensor consists of the temperature sensor. ### Claim 7 (depends on 5) The antimicrobial supply system of claim 5, wherein the sensor consists of the pressure sensor. ### Claim 8 (depends on 5) The antimicrobial supply system of claim 5, wherein the sensor consists of the air pressure sensor. ### Claim 9 (depends on 5) The antimicrobial supply system of claim 5, wherein the sensor consists of the flow sensor. ### Claim 10 (depends on 9) The antimicrobial supply system of claim 9, wherein the flow sensor senses a flow of the dilute concentrate supplied from the dilution reservoir to a manifold. ### Claim 11 (depends on 5) The antimicrobial supply system of claim 5, wherein the electronics control module is configured to receive data from the sensor. ### Claim 12 (depends on 11) The antimicrobial supply system of claim 11, wherein the electronics control module is further configured to log the data received from the sensor. ### Claim 13 (depends on 11) The antimicrobial supply system of claim 11, wherein the electronics control module is further configured to determine that the data received from the sensor deviates from a parameter associated with the sensor. ### Claim 14 (depends on 13) The antimicrobial supply system of claim 13, wherein the electronics control module is further configured to, responsive to a determination that the data received from the sensor deviates from the parameter, transmit, via a communication network, an alert signal to a remote system. ### Claim 15 (depends on 13) The antimicrobial supply system of claim 13, wherein the electronics control module is further configured to: receive, via a communication network, a control signal; and responsive to the control signal, adjust the parameter associated with the sensor. ### Claim 16 (depends on 11) The antimicrobial supply system of claim 11, wherein the electronics control module is configured to transmit, via a communication network, the data to a remote monitoring system. ### Claim 17 (depends on 1) The antimicrobial supply system of claim 1, further comprising a manifold coupling the output of the dilution reservoir to the at least one application system.
