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.
