Abstract
The Ontario Ministry of the Environment is actively investigating protocols for approving the installation of ultraviolet (UV) disinfection systems for drinking water disinfection. This paper discusses issues that may be considered for selecting the appropriate UV dose, validating UV reactor performance, and monitoring the performance of the reactor once installed.
The information presented in this paper has been adapted from a draft report commissioned by the Ontario Ministry of the Environment, Watershed Standards Division, to identify information needed for the development of UV drinking-water disinfection guidelines.
