Spring 2023
The increasing abundance of per- and polyfluoroalkyl substances (PFAS) has attracted growing interest due to concern about the potential hazards to public health and ecosystems. Due to PFAS toxicity, mobility, environmental persistence, and strong bioaccumulation, they are being further...

Conserving cougars in a rural landscape: habitat requirements and local tolerance in west-central Alberta
DownloadSpring 2011
Maintaining large carnivores in human-dominated landscapes poses a significant conservation challenge. Extirpation is common because of habitat loss or direct persecution. I studied cougar habitat selection and human perception of cougars in west-central Alberta to better understand...

Development of a hybrid wheat straw adsorption and microfiltration system for oily wastewater treatment
DownloadFall 2020
Effective, economical, and sustainable treatment technologies are highly desirable for treating oily wastewater generated from various industries as well as municipal and commercial establishments. The performance of traditional polymeric membranes is largely constrained by their high fouling...

Development of dynamic column breakthrough for multicomponent adsorption equilibrium and diffusion
DownloadFall 2022
Pressure and temperature swing adsorption processes are increasingly being designed and optimized computationally. The reliability of these predictions are highly dependent on the quality of the experimental equilibrium and kinetic data used in these simulations. Consistent experimental...

Effect of adsorbate’s polarity, steric hindrance, aromaticity, and boiling point on competitive adsorption in a multi-staged countercurrent fluidized bed reactor using activated carbon and zeolite
DownloadFall 2022
Understanding the multi-component adsorption of volatile organic compounds (VOCs) is of essential importance for real-world engineering applications. Various properties of VOCs can affect their competitive adsorption when there is a mixture of these compounds in the process stream. This thesis...
