1History of silver water treatment
The antimicrobial effect of silver has been known for thousands of years and was used by various cultures. As early as Alexander the Great (356–323 BC), drinking water was transported in silver vessels for his military campaigns.
In the 19th century, silver coins were placed in milk cans to extend shelf life. American pioneers placed silver dollars in their water containers.
Scientific research began in 1869 when Swiss botanist Carl Wilhelm von Nägeli coined the term "oligodynamic effect" – the germicidal property of metal ions in minimal concentrations.
