We’ve talked about what Legionella bacteria is and how to prevent Legionella from developing in your clients’ systems on previous podcast episodes (see list of episodes below), but what do you do when your building does test positive for Legionella bacteria? Over the past few months, the Scaling Up Nation has submitted dozens of questions on this topic, so on today’s episode, we’re answering your questions covering everything from what options to consider when treating Legionella bacteria in your client’s systems to what the drawbacks those three remediation techniques have; and many more listener-submitted questions during my interview with Dr. Alberto Comazzi.
For those of you who don’t know Alberto Comazzi, let me introduce you: 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 I cannot tell you how grateful I am to him for coming on the show today!
Bottom line: Albert knows exactly what you should do when treating a system that tests positive for Legionella bacteria.
