When was copper silver ionization water treatment discovered?

The modern application of Copper silver ionization technology was originally developed in the mid 1950s and has evolved since then. Being of smaller capacity at first, the more modern versions of CSI technology started to make their appearance in the late 1990s. In early 2000, ProCare Water Treatment Inc.(CANADA) was the first to launch a new era of modern copper silver ionization solutions under the brand name AquaLyse®. These powerful CSI units included unique engineering and automation features that propelled the advancements of Legionella growth control into facility potable water distribution networks. Over a decade later, CSIDefender® was introduced to the industry with additional automation features and innovative ionization chamber cell engineering.
