Anti-microbial device

A method for antimicrobial treatment of a fluid comprising:

• positioning a metallic coated substrate in a support frame for intimate contact with a porous body positioned with respect to the substrate for intimate contact of turbulated fluid in the porous body with the substrate, said support frame intermediate the substrate and porous body to support the metallic coated substrate adjacent the porous body;
• directing fluid via a housing containing the substrate, support frame and porous body with 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;
• aerating the fluid with 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 to provide a turbulated fluid at an inlet to the housing for turbulation in the porous body to produce a selected concentration of metallic ions in the fluid at an outlet of the housing;
• programming an electronic control and monitoring system including an electronic module 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 and,
• providing the fluid from the outlet of the housing for antimicrobial action.

An antimicrobial device comprising:

• a water pressure regulator connected to a hot water source;
• an air pressure regulator connected to an air inlet;
• a diffusion device containing hollow porous diffusion material having an inlet connected to receive water from the water pressure regulator, an inlet connected to receive air from the air pressure regulator and an outlet;
• a metallic coated substrate;
• a porous body positioned with respect to the substrate for intimate contact of turbulated water 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 connected to the diffusion device outlet and an outlet for the water, said substrate, support frame and porous body positioned for flow of the water through the porous body directly from housing inlet to housing outlet;
• a flow reducer connected to the outlet of the housing;
• and,
• an electronics module programmed to control the water pressure regulator, air pressure regulator and flow reducer to adjust corrosive properties of the combination of the water and air thereby varying concentration of metallic ions dissolved into solution in the water from the substrate between 1 ppb and 700 ppb.
