Copper Silver Analysis
Copper-silver ionization is a disinfection method that is used to eradicate Legionella from hot water recirculating systems. Disinfection with ionization occurs when the positively charged copper and silver ions released from the ionization system bind to the negatively charged cell wall of Legionella causing cell death. Ion concentration should be monitored to document that effective levels have been achieved and to avoid excess ion levels.
Suggested target ion range for Legionella control: Copper: 0.20–0.80 mg/L; Silver: 0.01–0.08 mg/L
Choosing the right sampling sites is important to ensure that the proper levels of copper and silver ions are being distributed to the entire water system so that maximum disinfection will be achieved.
