Patent ID: 8641967

Claim:
An antimicrobial device comprising: a metallic coated substrate; a porous body positioned with respect to the substrate for intimate contact of turbulated fluid in the porous body with the substrate; a support frame intermediate the substrate and porous body to support the metallic coated substrate adjacent the porous body; a housing containing the substrate, support frame and porous body and having an inlet and outlet for the fluid, said substrate, support frame and porous body positioned for flow of the fluid through the porous body from inlet to outlet; a fluid diffusion device containing hollow porous diffusion material connected upstream of the housing inlet and having fluid inlets for a first fluid and a second fluid creating a corrosive fluid for turbulation in the porous body; and, an electronic control and monitoring system including an electronic module programmed to adjust the corrosive properties of the combination of the first fluid and second fluid by controlling flow of the first and second fluids received by the fluid diffusion device for varying concentration of metallic ions dissolved into solution from the substrate between 1 ppb and 700 ppb.
