UV Reactor Challenges with Adenovirus: A Comparison of Adenovirus and MS2 Inactivation in Low Pressure and Medium Pressure UV Reactors
Adenovirus has been shown to have a high resistance to low pressure (LP) UV, and although not reported in any drinking water outbreaks, it has been chosen to define the UV dose requirements for virus credit in the US EPA LT2 ESWTR. Recently Linden and co-authors reported that A denovirus can be inactivated with lower UV doses when using medium-pressure (MP) polychromatic lamps. Working with Adenovirus Type 2, we verified the decreased UVresistance of Adenovirus to MP light sources compared to LP light sources using MP and LP collimated beams. In addition, we challenged LP and MP UV reactors with Adenovirus Type-2, in full scale challenges in a specially-controlled facility.
