Special Pathogens Laboratory sets the industry standard for Legionella disinfection technologies. Since the early 1990s, our studies have been published in numerous peer-reviewed, major scientific and medical journals, and trade journals. Following are disinfection technologies and products that have been shown to effectively reduce the presence of Legionella in water systems.
Monochloramine has been used successfully for municipal water treatment. Now a commercial system for treatment of single buildings has been developed by Sanipur (Brescia, Italy). Dr. Stout presented findings of the first U.S. study of this monochloramine generating system for Legionella disinfection at the annual Association of Water Technologies conference in September 2012. The results showed a significant decrease in Legionella percent positivity of the hospital's hot water system soon after installation.

Research conducted by Special Pathogens Laboratory showed that Legionella can be successfully controlled by chlorine dioxide. The time needed to achieve requisite reduction in percent positivity is site specific and dependent on whether the application point is on the cold water, hot water or a combination.

Research by Special Pathogens Laboratory showed that focal disinfection with UV light could reduce Legionella in a hospital when combined with a systemic disinfection method. Read:Legionella in Water Distribution Systems.
