The primary objective of this study was to demonstrate the use of fluorescent-dyed microspheres in a full-scale ozone contactor. Experimental results obtained with the microsphere surrogates can be used to validate mathematical models developed to predict the inactivation of C. parvum oocysts in ozone bubble diffuser contactors, which can then be used for optimizing the contactor performance in terms of disinfection efficiency (Kim et al., 2002a,b) and bromate minimizaiton (Kim et al., 2001). The correlation developed with bench-scale experiments between microspheres fluorescence decay kinetics and C. parvum oocyst inactivation kinetics, as well as some preliminary results obtained from full-scale demonstration tests are presented in this paper. Includes 12 references, figures.
