Contaminant Degradation Models: ENVR 400 In-House Seminar

January 30, 2019 @ 12:20 pm - 1:10 pm

Alex Gorzalski, a doctoral candidate in the Department of Environmental Sciences and Engineering, will present this week’s seminar in the department’s Spring 2019 series. Gorzalski’s talk is titled, “Improving Accuracy of Contaminant Degradation Models in Water Treatment.”

Abstract: The disinfection of drinking water was one of the greatest public health achievements of the 20th century. The inactivation of pathogenic microorganisms was achieved by the addition of a disinfectant, usually chlorine, to water for a prescribed amount of time. Despite its importance in the field of water treatment, the models used in disinfection regulation and system design remain rather rudimentary. This may result in an inaccurate quantification of pathogen inactivation. Further, disinfection processes are being relied on for new applications, including the degradation of reactive contaminants and the reuse of wastewater as drinking water. With new applications comes an opportunity to
more accurately predict contaminant degradation in water treatment using improved models. This presentation will discuss the introduction of reactor network models to the water treatment field. The effect of model selection on predictions of non-reactive tracer behavior, reactive tracer behavior, and contaminant degradation will be discussed. This research highlights the importance of model selection in improving the accuracy of contaminant degradation predictions in water treatment.
