Copper silver ionization is a non-chemical supplemental water treatment technology regarded as the most clinically effective prevention and remediation solution for Legionella, the bacteria responsible for Legionnaires' disease (Legionellosis). During this treatment, ions are systematically introduced into the water using a byproduct-free method to rid plumbing infrastructure of Legionella bacteria and other waterborne pathogens.

Copper silver ionization water treatment is the most effective technology for systemic disinfection of Legionella in potable water systems. In field evaluations, this technology has yielded the best results over a wide range of water conditions and temperatures, and is backed by more than 100 independent research studies. A copper silver ionization unit introduces disinfectant ions to travel throughout the plumbing infrastructure and attack Legionella living downstream, embedded in various parts of the plumbing distribution system. CSI does not require consumables that are unsafe for handling. The ions introduced into the water supply are safe for human consumption and will not cause damage to the plumbing environment.

LiquiTech’s® system has undergone years of intense scrutiny and analysis in the U.S. and around the world. More than 100 independent research articles have verified that this process is the most clinically effective prevention and remediation solution for Legionella. It is currently recognized by the U.S. Environmental Protection Agency as having satisfied efficacy requirements to be able to make claims about the killing of Legionella.

All flow cell wetted parts are NSF standard 61-certified. The Department of Defense selected this process as a requirement for all new healthcare projects in its Unified Facilities Criteria. Abroad, the system is certified for the remediation of Legionella from drinking water by the Dutch Competent Authority CTGB. All components of the ionization chamber are KIWA-ETA-approved.

How does it work? The ions produced by the LiquiTech ionization process are cationic, surface-active, and a potent biocide. The treatment action is attributable to the positively charged copper and silver ions forming electrostatic bonds with negatively charged sites on microorganism cell walls. These electrostatic bonds create stresses that lead to distorted cell wall permeability, disrupting the intake of life-sustaining nutrients, and ultimately leading to cell lysis. Bacteria are killed, rather than merely suppressed as is the case with alternative Legionella treatment methods. The accurate dose-rate control system maintains precise ion levels, providing residual protection and prevention of recontamination.

Copper silver ionization has no harmful by-products, is eco-friendly, and safe. Copper silver water treatment is the safest and most eco-friendly solution to water protection. Comparatively, this method requires no chemicals, whereas hyperchlorination requires extensive dosage measurements. Hyperchlorination functions by injecting high doses of chlorine to disinfect a water system. However, research shows that approximately 70% of chlorine dioxide degrades in hot water. Therefore, you’d need to add a high concentration of 2 to 4 ppm of chlorine to sustain efficacy. Maintaining such high concentration is difficult and creates by-products which proven to be carcinogenic. During copper silver ionization, copper and silver are added into the water supply at doses of approximately 0.3-0.4 ppm, thereby preventing harmful by-products, carcinogenic risks, and negative health-related side effects.

Copper silver ionization has no corrosive effects. Most chemical solutions are proven to be corrosive to your plumbing infrastructure in the long-term, causing pinhole leaks and other costly issues that require equipment replacements. Disinfection imposes a high voltage, which may damage the lids and pumps in a system. A common misconception about copper silver ionization is that the copper ions have corrosive effects. This is simply not the case as proven by industry data time and time again (add link to data). After 25 years of successful installations, this technology has not once caused any corrosion issues. In fact, it keeps the plumbing intact to ensure longevity in the life-span of your plumbing.
