1- The Ionisation process of copper and silver is provoked when these metals are electronically stripped of electrons and become positively charged (Cu++, Ag+).

2- By running a DC voltage between the sacrificial copper and silver electrodes submerged in water, positively charged metallic copper and silver ions are created and released into the water.

3- Having a water flow between the electrodes carries away the metallic ions into the water system before they can reach the opposite electrode.

4- Once replaced within a water reservoir or distribution network, the positively charged copper and silver ions are attracted to negatively charged particles such as Legionella bacteria and commence the biocide process upon contact.
