Bench to pilot scale-up: impact on microbial inactivation
01 Jan 1993
Abstract
Bench and pilot-scale inactivation studies were carried out on 3 different waters using 3 different disinfectants to develop a model of the disinfection process for predicting continuous flow system performance. The disinfectants were free chlorine, monochloramine and ozone, and the water included a buffered, zero-oxidant-demand water, Bull Run water used for the supply to the city of Portland, and water from the Willamette river, upstream from Portland city. Cultured cells of Escherichia coli and bacteriophage MS2 were used as targets for disinfection and Giardia muris cysts were also added to the samples. The Horn model of disinfection performance provided a useful predictive tool and the use of inactivation kinetic parameters obtained from bench-scale studies could be used to predict the performance of a pilot-scale continuous system treating water from the same source, within the limits of experimental error. However, kinetic parameters obtained using buffered oxygen demand-free water were not representative of those of natural waters and were thus of no predictive significance. Certain values for Ct products obtained during the bench-scale studies also differed from those in the official procedures for application of the Surface Water Treatment Rule.
