The kinetics of Cryptosporidium parvum oocyst inactivation and bromate formationhas been the subject of intensive research efforts in recent years. Computer modeling has been employed to predict, in particular, the ozone-induced formation of bromate because of the complexity of the mathematics involved. However, most of the previous studies have been confined to a laboratory-scale ozone contactor in which hydrodynamic conditions were often designed to be ideal. An integrated computer simulation was recently attempted for a batch ozone contactor and a flow-through bubble-diffuser reactor with external recirculation. Both models have been verified with ozone decomposition, bromate formation, and C. parvum inactivation data using phosphate-buffered DDI water in the laboratory-scale batch and flow-through ozone contactors. The overall objective of this study is the development and application of an integrated model to simultaneously predict C. parvum oocyst inactivation and bromate formation in full-scale ozone contactors. A detailed description of the model is presented. Includes 22 references, table.
