The ultraviolet (UV) dose delivered by a UV disinfection system can be predicted by computational fluid dynamics
(CFD) and UV intensity models for varying UV transmittance (UVT), inactivation kinetics and system
operating conditions. This study involved CFD modeling to evaluate the effect of these factors on the
reduction equivalent dose (RED) and RED bias of two UV system designs. The RED bias is a correction
factor that accounts for differences in the RED for the challenge microbe used during reactor validation
and the target pathogen RED. Results indicate that RED bias significantly decreases as the UVT increases
and as the UV sensitivity of the challenge microbe approaches that of the target microbe. Results also
demonstrate that RED bias varies from reactor to reactor.
