With the combination of the 2 components, Copper and Silver, the capacity of disinfection increases in such that it amplifies the efficiency of each one of our systems, and, as well, in the case of cold water, it is supported by the presence of a third combinable component (chlorine), the disinfectant progression is geometric.

Adding metals to water as disinfectants seems to come from ancient times where the Phoenecians put silver and copper coins into the ceramic ampHoras to conserve the water.

The Greeks discovered that putting copper coins in the large earthen vats the water didn’t corrode. The Egyptians placed on the other hand silver coins in order to prevent contamination.

In the Middle Ages the mothers knew to feed their children with silver spoons to protect them from many illnesses.

Many airlines use silver ions to protect the drinking water they give to passengers on their flights. In over 70 countries silver ions are added to drinks, beers, liquors, and wines.

In America, during the colonization of the old west, the custom of placing a silver dollar in the water barrels for conservation also existed.

Oxidation Reactions

The producing reaction of ions (in the anode)

Cu++ Cu2+ + 2e-

Ag++ Ag+ + 1e-

James C.V. 1.971, stated that all silver salts are antibacterial and that silver particles dissolved in was in a concentration of 10-5 is toxic for E. Coli and Baciillas types.

The Cu/Ag ionization technology available today, was developed by NASA in the beginnings of the space program, with the goal being to have a safe way of purifying water to bring into space.
