Mixed Oxidant and Chlorine Dioxide Levels Necessary for Legionella Control

Mixed oxidant and chlorine dioxide are some of the leading disinfectants for Legionella control. See the below chart for concentration levels and efficacy for Legionella control. The target concentration level is .5 ppm or above for both of these disinfectants. At this level, Legionella is typically killed in the water and biofilm is greatly reduced. Reaching a level of .5 ppm of these disinfectants at the fixtures typically results in Legionella being killed in the water and biofilm being effectively removed.
