285 Re-Release of What To Do When Your System Tests Positive For Legionella


Alberto ComazziWe’ve talked about what Legionella bacteria is and how to prevent Legionella from developing in your clients’ systems on previous podcast episodes, but what do you do when your building does test positive for Legionella bacteria? We’ve had so many questions about this topic that the Scaling UP! H2O team decided to re-release our most listened-to episode on this topic.

Dr. Alberto Comazzi answers dozens of listener-submitted questions about what to do when your system tests positive for Legionella, and what options water professionals need to consider when treating Legionella bacteria in your client’s systems.

For those of you who don’t know Alberto Comazzi: he is a member of the ASHRAE SSPC 188 committee, AWWA premise plumbing committee, and the AWT pre-treatment committee. Alberto is certified to ASSE/IAPMO/ANSI 12080 Legionella Water Safety and Management Personnel. The author and co-author of fifteen scientific papers, and the Technical Director at Sanipur US, based in Philadelphia PA, Alberto was the first person I thought to have on the show to answer questions about treating systems positive for Legionella. 

Alberto Comazzi has a Ph.D. in Industrial Chemistry from the University of Milan, Italy. His research during his academic experience was focused on the study of the stability and the interaction among different chlorine-based water disinfectants. He has presented at over 20 conferences and there was no one our listeners enjoyed learning from more on the topic of Legionella than Alberto.

Bottom line: Alberto knows exactly what you should do when treating a system that tests positive for  Legionella bacteria.

Thinking On Water With James: 

In this week’s episode, we’re thinking about infrared thermometers or guns. Why would you want to use an infrared thermometer on industrial water systems? What pieces of equipment should they be used upon? How far away are they accurate? What does the distance-to-spot ratio tell you about the size of area the infrared thermometer is measuring? How does the design of the steam trap impact where and what temperatures you should see around a trap? Take this week to think about infrared thermometers, their strengths, weaknesses, and uses.
