Pennetta de Oliveira, Leonardo
Bitumen has been extensively extracted from oil sands through the Clark Hot Water Extraction (CHWE) process. This extraction process uses hot water and alkaline conditions to remove bitumen from oil sands ores. The tailings produced by this process are mixtures of sand, clays, residual bitumen,...

Combined Adsorption and Biodegradation Processes for Oil Sands Process-Affected Water Treatment
DownloadFall 2014
The oil sands process-affected water (OSPW) generated from bitumen extraction of oil sands by industries in Northern Alberta, Canada, is a great environmental concern because of the OSPW toxicity in the environment. This toxicity has been attributed to a group of alicyclic and aliphatic compounds...

Abdelrahman, Ali Satti Abdellatif
In northern Alberta, the bitumen extraction process from oil sands ores consumes large amounts of water, resulting in the generation of huge volumes of oil sand process water (OSPW). Currently, the treatment of OSPW is considered a major challenge facing the oil sands industry. Moreover, among...

Development of compact fluorescent spectrometers and field deployable optical solids content monitoring devices
DownloadSpring 2015
Two techniques were used to develop industrial and environmental sensing devices: fluorescence spectrometry and light scatter. The focus of the thesis is to develop real-time, portable and economical sensors using these techniques for environmental detection and management of tailings slurries. A...

Effects of Surface Contamination and Water Chemistry on the Behaviors of Illite, Kaolinite and Montmorillonite in Organic and Aqueous Media
DownloadSpring 2016
Clays, due to their specific surface area and electrical charge density, are among the most active minerals in aquifers, oil and gas reservoirs, and tailings ponds. Clays, in tailings, are a significant ongoing environmental concern in the mining and oil sands production industries and clay...

Anthropogenic contaminants can impair olfactory responses to natural odorants. In fishes, these impairments may be used as a metric of sub-lethal toxicity. My studies aimed to determine the effects of two contaminant sources on fish olfaction as measured by electro-olfactography (EOG). The...
