CFD design approach for chlorine disinfection processes

摘要: Current approaches for chlorine disinfection process design involve application of a C x T (concentration time) concept or the integrated framework (IDDF) (Bellamy et al, 1998). This study presents new approach that uses computational fluid dynamics (CFD). CFD models were developed to predict flow structure, mass transport, decay, and microbial inactivation in continuous-flow reactor associated piping. Past have only predicted contactor structure residence time distribution (Crozes 1999; Wang & Falconer, 1998; Hannoun Boulos, 1997; Stambolieva 1993). The model described here incorporates experimentally derived terms decay (free combined) (Escherichia coli, MS2 bacteriophage, Giardia muris) based on work Haas al (1995). predictions good agreement with experimental data set over wide range rates.
