Chlorine Dioxide for Legionella Control

The study evaluates the safety and efficacy of chlorine dioxide for controlling Legionella in a potable water system within an acute care hospital environment. It examines chlorine dioxide, its by-products, and their impact on Legionella, pathogenic bacteria, biofilm, medical and laboratory filtration systems, corrosion rates, and the environment.

Corrosion Monitoring: Corrosion monitoring was conducted using copper and mild steel coupons placed in bypass racks to assess the impact of chlorine dioxide on these materials.

Water Quality Monitoring: Water quality monitoring, including Legionella and bacterial culturing, was performed at multiple sites in the building over a 46-month period.

Key Findings: The data obtained from the study demonstrated the effectiveness of chlorine dioxide in controlling Legionella and pathogenic bacteria in the hospital potable water system.

This summary provides an overview of the study’s findings on the use of chlorine dioxide for Legionella control in a hospital setting.
