Upstream piping configuration has been known to impact the ultraviolet (UV) reactor
validation using biodosimetry tests. However, the influence of upstream configuration on
the UV dose distribution has not been experimentally investigated. This research was
performed to evaluate the UV reactor dose distribution under multiple upstream
configurations using UV sensitive fluorescent microspheres. The upstream hydraulics
configurations included two kinds of 90 degree bends and one straight pipe configuration.
Experimental tests were performed at 51 gpm flow rate, 91% UV transmittance (UVT) on
a single lamp low-pressure high-output (LPHO) UV reactor. The results of this study
showed that the straight pipe configuration produced a shift in UV fluence distribution to
a higher UV fluence range compared to the two elbow configurations. No significant
difference was observed between the two elbow configurations. The fluorescent
microspheres Bayesian method can serve as an additional test to the traditional
biodosimetry for UV reactor validation and added confidence in the experimental results
by providing unbiased UV dose behavior. Includes 19 references, tables, figures.
