Abstract
The influence of wall biofilms on the transport of pathogens through a water pipe is mathematically described using an attachment — detachment model. The process coefficients of attachment and detachment are estimated from experimental data. A biofilm annular reactor model is presented and model predictions are compared to experimentally derived bulk phase and biofilm-sorbed pathogen data. The resulting pair of parameters, through minimizing the weighted root mean square error, are used in a single pipe model, and the results are discussed.
