Strategy and Method for the performance
- Knowledge of the UV resistance of relevant pathogenic and indicator microorganisms Investigation under controlled conditions in a UV laboratory irradiation apparatus)
- Determination of a minimum UV Fluence (based on the required log reduction for pathogens)
- Selection of a suitable biodosimeter (UV-253,7 nm calibrated microorganism)
- Development of a biodosimetric method (controlled operation conditions) to determine the Reduction Equivalent Fluence (REF; J/m²)
- Full scale Performance Test of a UV system using the biodosimetric method
- Determination of the permissible range of operation of the tested UV system
(flow, UV-transmittance, UV irradiance)
Biodosimetric type test
