Researchers have previously demonstrated the importance of combining ultraviolet (UV) reactor hydraulics
with dynamic fluence rate models to predict the effectiveness of the disinfection process. A
recent AwwaRF study that successfully applied UV-initiated advanced oxidation for the
degradation of organic contaminants recognized the dependence on non-ideal reactor
characteristics (hydrodynamics and fluence rate) for the overall advanced oxidation processes (AOP) performance (Linden, et
al., 2004). Sharpless and Linden (2003) concluded that development of a predictive UV/AOP
model that incorporates reactor hydraulics would allow design simulations that optimize lamp
placement, minimize light screening, and improve prediction of contaminant removal in different
UV reactors. The research presented herein develops the protocol for using CFD models to
simulate UV-initiated AOPs by combining reactor hydraulics, fluence rate distribution, and
chemical kinetics. As oxidation pathways for emerging water contaminants are identified, a
simulation model, such as the one described, will become an important technique for the
evaluation, design, and optimization of advanced oxidation systems. Includes 39 references, figures.
