Performance and Energy Consumption Analysis of UV-H2O2 Photoreactors Using Computational Fluid Dynamics

M. Moghaddami and M. Raisee

Abstract—Advanced Oxidation Processes (AOPs) promoted by ultraviolet light are innovative and potentially cost-effective solutions for treating persistent pollutants recalcitrant to conventional water and wastewater treatments. While several studies have been performed during the past decade to improve the fundamental understanding of the UV-H2O2 AOP and its kinetic modeling, Computational Fluid Dynamics (CFD) has only recently emerged as powerful tool that allow a deeper understanding of complex photochemical processes in environmental and reactor engineering applications. In this investigation, a comprehensive kinetic model of UV-H2O2 AOP was coupled with the Reynolds Averaged Navier-Stokes (RANS) equations and UV fluence rate model using CFD to predict the oxidation of tributyl phosphate (TBP) and tri (2-chloroethtyl) phosphate (TCEP) in two different photoreactors: namely a parallel- and a cross-flow UV device employing a UV lamp emitting primarily the 253.7 nm radiation. The calculation of the fluence rate field was carried out by solving the irradiative transport equation (RTE) using the discrete ordinate (DO) model. Notably, the fluence rate model assumes a fluid with a spatially dependent absorption coefficient that is function of the H2O2 and HO2- species concentration. The oxidation performance of both reactors is computed and the Electrical Energy per Order (EEO) is computed for the comparison of the reactors and it is found that the EEO of the cross flow reactor is greater.
