Another key use for silver is in the millions of water purifiers that are sold each year. Silver prevents bacteria and algae from building up in their filters so that they can do their job to rid drinking water of bacteria, chlorine, trihalomethanes, lead, particulates and odor. Research has shown that the catalytic action of silver, in concert with oxygen, provides a powerful sanitizer that virtually eliminates the need for the use of corrosive chlorine.
Silver ions are also starting to be added to water purification systems in hospitals, community water systems, pools and spas. It is slowly replacing chlorine as the widespread element of choice for filtration. Silver also eradicates Legionnaires’ disease, which is caused by buildup in pipes, connections and water tanks.
Water-born illness is a major problem in developing nations. The full extent to which silver can help treat the issue of clean drinking water has yet to be seen but ongoing research is showing its usage to be an exciting development for the global water supply.
