The Challenge
- Quarterly tests showed Legionella above the 1 CFU/mL target
- Average contamination level reached 7 CFU/mL
- Flushing and equipment replacement were expensive
- A $75,000 treatment system was being considered
The Solution
A HydroFLOW® i100 was installed in July 2022 on the 4 inch potable water line entering the building, with a HydroFLOW® S38 serving 14 ice machines, as part of a 90 day proof of concept. Treatment reduces the biofilm growth linked to Legionella, so counts fell to 1 CFU/mL or non detectable within 16 days.
