Abstract

A new, novel and useful disinfection and purification system comprised of organic compounds in synergistic action with selected metal ions and method of manufacture and use. One of the benefits that is derived from this system is the ability to quickly and easily treat a surface, fluid or medium for disinfection of bacteria, fungi, viruses, algae and protozoans, with a non-toxic, non-chlorinated mixture that effectively kills all such organisms in minutes or hours. The disinfection and purification system remains effective for long periods of time maintaining its disinfection capacity making it highly effective for stored or transported mediums such as potable drinking water. The disinfection and purification system may be incorporated with carbon block or membrane filters to disinfect filtered liquids such as water to render it potable. The disinfection and purification system may be infused into semi-permeable surfaces or applied to non-porous surfaces such that the disinfectant compounds of the system would be delivered to surface of an object to be disinfected by leaching, capillary action, mere contact, water activation and/or osmosis/diffusion.

Claims

1. A disinfection and purification composition comprising:

(a) copper and silver dissolved in a fluid, wherein a ratio of copper ions to silver ions in the disinfection and purification composition is from 1;

1 to 50;

1;

(b) grapefruit seed extract; and

(c) glycerin,

wherein the amount of glycerin on a weight basis is less than or equal to 2.75 times the amount of grapefruit seed extract on a weight basis.

2. The composition of claim 1, wherein no more than 110 milligrams of grapefruit seed extract is dissolved in the fluid per liter of the fluid.

3. The composition of claim 1, wherein no more than 220 milligrams of glycerin is dissolved in the fluid per liter of the fluid.

4. The composition of claim 1, wherein a ratio of copper ions to silver ions in the disinfection and purification composition is 20:

1.

5. The composition of claim 1, wherein no more than 0.75 milligrams of copper is dissolved in a fluid per liter of the fluid.

6. The composition of claim 1, wherein no more than 0.0375 milligrams of silver is dissolved in a fluid per liter of the fluid.
