Frequently asked questions

What is secondary disinfection in building water systems?

It’s the continuous application of disinfectants, such as monochloramine or chlorine dioxide, to prevent the growth of Legionella and other pathogens.

When is secondary disinfection required?

When primary treatment is not enough, or when facilities need to comply with standards like ASHRAE 188 and AAMI ST108. It’s also common after repeated positive Legionella tests.

What methods are used for secondary disinfection?

Monochloramine, chlorine dioxide, free chlorine, and onsite generation systems are the most common approaches.

Is secondary disinfection safe and sustainable?

Yes. Modern secondary disinfection systems reduce hazardous chemical handling and use sustainable treatment methods that reduce environmental impact while maintaining effective pathogen control.

How is secondary disinfection monitored?

Systems include probes, controllers, and remote monitoring that provide real-time data, alarms, and detailed reports to keep facilities audit-ready.
