Legionella prevention through chlorine dioxide in hotel
Because the problem with water contamination by Legionella increases, the Queens Hotel in Baden-Baden, Germany, set itself the task of keeping all water pipework systems safely sterilised.
ProMinent designed and implemented an extensive, complete solution for Legionella prevention based on chlorine dioxide disinfection.
Challenge
- Sustained avoidance of biofilms and the associated breeding grounds for Legionella in hot and cold water pipework systems
- Extensive multi-branch pipework system covering five floors
Solution
- Central Bello Zon® chlorine dioxide production and dosing system to supply the individual injection points
- Disinfection of the hot and cold water in accordance with the Directive on potable water
- Monitoring of the chlorine dioxide dosing using DULCOTEST®/DULCOMETER® measurement and control technology
- Documentation of the chlorine dioxide content at the furthest measurement point using a videographic recorder
Customer benefits
- Reliable, monitored and documented disinfection of the hot and cold water
- Microbiological safety in the water and in other parts of the plant (pipes, boiler, filter)
- Elimination of thermal disinfection
- Reduction in staffing levels
