Under electronic monitoring and control, fluids flow into a fluid diffusion device 9 to form a fluid combination. The fluid combination has corrosive properties as it flows into an anti-microbial canister 8 housing a roll 4 of anti-microbial metallic coated substrate 1, support frame 2, and porous body 3. The fluid combination corrodes the anti-microbial metallic coated substrate 1 located inside the anti-microbial canister 8. Upon exiting the anti-microbial canister 8, the fluid combination contains dissolved metal and is a liquid anti-microbial agent. ...
