Guidelines and Compliance for Copper-Silver Ionization
Copper-silver ionization technology is recognized by the World Health Organization (WHO) and the U.S. Environmental Protection Agency (EPA) for controlling Legionella in potable water systems. The ion levels generated are usually below the EPA’s Safe Water Drinking Act Lead and Copper Rule Action Level for copper, which is 1.3 ppm, and the Secondary Contaminant Level for silver, which is 0.1 ppm.
Maintaining Optimal Ion Levels
Accurate sample collection and handling are crucial for reliable results. Leading manufacturers of copper-silver ionization technology recommend maintaining copper concentrations between 0.2 to 0.8 ppm and silver concentrations between 10 to 80 ppb, ensuring compliance with EPA drinking water standards.
Copper-Silver Ionization in Europe
In Europe, the British Health and Safety Commission regulates ionization, advising regular system monitoring to ensure ions reach all water circuits. The European Community limits copper in drinking water to 2 ppm, while Legionella control requires much lower concentrations, ensuring safety. Although the European Union’s decision in 2012 temporarily halted copper use as a biocide due to industry documentation issues, several member states have since applied for its continued use.
Ongoing Efforts for Compliance
The UK Health and Safety Executive has informally granted a derogation application, allowing continued use of copper as a biocide. Industry leaders are working to ensure full compliance with European regulations through a dedicated Taskforce.
The Process of Copper-Silver Ionization
Copper-silver ionization works by dispersing positively charged copper and silver ions into the water system. These ions bond with bacterial cell walls, denaturing proteins and destroying biofilms and slimes that harbor Legionella. Over time, copper and silver ions penetrate biofilms, effectively eradicating Legionella bacteria.
Maintenance and Implementation
Maintaining the ionization system involves periodic cleaning of flow cells.
