Description
Researchers have previously demonstrated the importance of combining ultraviolet (UV) reactor hydraulicswith dynamic fluence rate models to predict the effectiveness of the disinfection process. Arecent AwwaRF study that successfully applied UV-initiated advanced oxidation for thedegradation of organic contaminants recognized the dependence on non-ideal reactorcharacteristics (hydrodynamics and fluence rate) for the overall advanced oxidation processes (AOP) performance (Linden, etal., 2004). Sharpless and Linden (2003) concluded that development of a predictive UV/AOPmodel that incorporates reactor hydraulics would allow design simulations that optimize lampplacement, minimize light screening, and improve prediction of contaminant removal in differentUV reactors. The research presented herein develops the protocol for using CFD models tosimulate UV-initiated AOPs by combining reactor hydraulics, fluence rate distribution, andchemical kinetics. As oxidation pathways for emerging water contaminants are identified, asimulation model, such as the one described, will become an important technique for theevaluation, design, and optimization of advanced oxidation systems.
