Fall 2009
The work presented in this dissertation provides a novel technique of manipulation of colloidal entities during membrane filtration based on an AC electrokinetic phenomenon called dielectrophoresis. First, the influence of dielectrophoretic (DEP) forces created on a membrane surface to levitate...

Application of Anoxic-Aerobic Membrane Bioreactors (MBRs) for Oil Sands Process-Affected Water (OSPW) Treatment
DownloadFall 2016
The enormous volumes of oil sands process-affected water (OSPW) produced during oil sands bitumen extraction have been a public concern due to the toxicity and persistence of the organic contaminants contained in the water. Among all the contaminants in OSPW, naphthenic acids (NAs) are regarded...

Application of Ozone and Peroxone Processes for Naphthenic Acids Degradation in Oil Sands Process-Affected Water: Characterization of Water Before and After Treatment
DownloadFall 2017
Appling ozone (O3) with high doses (>100 mg/L) to remove naphthenic acids (NAs) from oil sands process-affected water (OSPW); limits its application and feasibility in the OSPW remediation. To decrease the required doses and their associated costs, this study examined the application of ozone...

Characterization of natural zeolite membranes for H2/CO2 separations by single gas permeation
DownloadFall 2011
Hoseinzadeh Hejazi, Sayed Alireza
Membrane-based processes have the potential to overcome the limitations of conventional hydrogen separation techniques such as high energy consumption and environmental concerns. Natural zeolite membranes have recently been shown to demonstrate apparent molecular sieving of H2 from H2/CO2...

Development and application of Fenton and UV-Fenton processes at natural pH using chelating agents for the treatment of oil sands process-affected water
DownloadFall 2016
The increasing amount of oil sands process-affected water (OSPW), its high toxicity towards aquatic organisms due to naphthenic acids (NAs) and other organics, and the zero discharge practice of the oil sands industry urge researchers to seek effective approaches for its treatment. Advanced...

Fall 2018
The fluids produced from a thermal enhanced recovery process such as steam assisted gravity drainage (SAGD) and cyclic steam stimulation (CSS) are pumped to the surface where bitumen and water are separated. This initial fluid is known as SAGD-PW (produced water). A potential way to effectively...

Forward Osmosis as an Approach to Manage Oil Sands Produced Water: Membrane Fouling and Organic Removal
DownloadFall 2017
Currently, large amounts of oil sands process-affected water (OSPW) are stored in tailing ponds, leaving its environmental impact a significant concern. To better manage OSPW, numerous treatment approaches have been investigated including adsorption, advanced oxidation and biological treatment,...

Natural zeolite-based membranes have recently shown promise in the separation of H2 from CO2 and hydrocarbons. However, these highly dense, naturally monolithic materials can suffer defects which disrupt the continuity of the zeolite micropores and create leak paths through the membrane. Cement...

Investigation of the Adsorption of Model and Oil Sands Process-Affected Water Naphthenic Acids on Graphite
DownloadSpring 2015
Naphthenic acids (NAs) are constituents of bitumen in the oil sands deposits in northern Alberta, Canada. The extraction process of bitumen creates an enormous amount of wastewater called oil sands process affected waters (OSPW). This OSPW contains elevated concentrations of NAs, and other...
