Copper-silver Ionization

The Most Effective Solution for Legionella Control

Copper-silver ionization is a disinfection process, primarily used to control Legionella, the bacteria responsible for Legionnaires' disease. There is strong evidence that treating water supplies in hospitals with this technique decreases the risk.

What Is Copper Silver Ionization Water Treatment?

Copper-silver_ionization - CSIDefender

Copper silver ionization water treatment is a method for disinfection commonly used to control Legionella bacteria in building water systems.

The Effectiveness of Copper-Silver Ionization

Copper-silver ionization is a highly effective method for controlling Legionella in potable water systems found in healthcare facilities, hotels, nursing homes, and large buildings. Studies indicate that copper-silver ionization is superior to thermal eradication methods, providing a more reliable solution for Legionella control.

Proven Results in Legionella Control

Multiple reviews highlight that copper-silver ionization consistently outperforms other methods, ensuring safer potable water in various types of facilities.

How does Copper Silver Ionization work?

Copper-silver ionization process introduces positively charged copper and silver ions into the water. This water treatment technology effectively kills Legionella bacteria and prevents its growth without the use of harmful chemicals.

CSIDefender® is a highly effective, environmentally friendly Legionella compliance solution that has been proven to maintain water safety and quality across a variety of facility types, including healthcare, hospitality, and residential buildings.

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.

Historical Context and Modern Adoption

Legionella Compliance Solutions - CSIDefender

Copper-silver ionization is a modern implementation of ancient Greek practices, using silver to reduce bacteria and copper to control algae and fungi. This method has proven effective in swimming pools and is increasingly adopted by municipalities. Copper-silver ionization is more convenient and cost-effective than chlorination or thermal eradication.

Regulatory Compliance

Legionella legal implications - CSIDefender

Copper-silver ionization can operate within the copper Action Level (AL) and silver secondary maximum contaminant levels (SMCLs) set by the U.S. EPA, ensuring compliance with the Safe Water Drinking Act’s Lead and Copper Rule. This technology provides a robust solution for maintaining safe and compliant potable water systems.
