Monochromatic low pressure (LP) and polychromatic medium pressure (MP) ultraviolet
(UV) lamp based UV reactors are two commercially available UV systems which are currently
being widely used to market water treatment. To ensure proper design and optimize
reactor performance, it is important to develop approaches for accurately estimating
the germicidal fluence rate distribution within the UV reactor for these UV systems.
Spherical actinometry is a technique for determining UV fluence using spherical quartz
vessels containing a chemical actinometer. This research combined the spherical
actinometry containing iodide/iodate and uridine actinometer with previously developed
mathematical analysis to measure germicidal fluence rate distribution in monochromatic
and polychromatic UV reactors. Initial results indicated good agreement using two
actinometers and reasonable prediction of the fluence rate as compared to previous
literature data. The method will be further used to verify the fluence rate distribution
predicted in mathematical modeling of UV reactors.
