ABSTRACT
The efficacy of disinfection processes in water purification systems is governed by several key factors including reactor hydraulics, disinfectant chemistry and microbial inactivation kinetics. The objective of this work was to develop a computational fluid dynamics (CFD) model to predict flow structure, mass transport and chlorine decay in a continuous flow pilot scale reactor. These predictions were compared with experimental measurements for model validation. The current research demonstrates that inlet configurations can significantly impact reactor hydrodynamics.
