Fall 2017
Water contamination by ammonium ions presents huge risks to the ecosystems. This work evaluated the potential application of digested sludge pyrolyzed biochar on ammonium removal. Anaerobic digester sludge was collected from a municipal wastewater treatment plant in Alberta, Canada and pyrolyzed...

Application of Electro-oxidation for the Degradation of Organics in Oil Sands Process Water (OSPW)
DownloadFall 2019
Large volumes of oil sands process water (OSPW) are generated during the extraction of bitumen from the mined oil sands ores in northern Alberta. The treatment of OSPW is currently considered a serious challenge facing the oil sands industry in the region. Among the different constituents in...

Fall 2014
The extraction of bitumen from oil sands in Alberta, Canada, leads to the creation of tailings that are contained in lake-sized ponds under zero discharge policy. Stratification of tailings over time leads to the formation of mature fine tailings (MFT), an oil based emulsion containing residual...

Applications of Remote Hyperspectral Sensing in the Characterization of Alberta's Oil Sands Tailings
DownloadSpring 2016
The bitumen production from oil sands surface-mining operations produces large volumes of mineral wastes called tailings. Characterization of the oil sands tailings is of importance to monitor their state for trafficability and reclamation issues, to assess the tailings operation performance, and...

Assessing the mobility of metals and dissolved organics in pit-lake models containing PASS-treated fluid tailings
DownloadSpring 2024
Oil sands surface mining produces considerable quantities of fine fluid tailings (FFT). Several reclamation strategies are being investigated to address the environmental concerns related to long-term FFT storage. One promising sustainable tailings management approach is End Pit Lake (EPL);...

Biological Treatment of Naphthenic Acids and Other Organic Compounds in Oil Sands Process-Affected Waters
DownloadFall 2014
The Alberta oil sands contain one of the world’s largest reserves of oil - over 169 billion barrels of bitumen are economically recoverable with current extraction technologies. Surface mining, whereby the ore is extricated from the earth and bitumen is obtained via a hot water extraction...

Bioremediation of oil sands process affected water sourced naphthenic acid fraction compounds
DownloadFall 2020
Current development of Alberta’s oil sands region requires large volumes of water, leading to an abundance of oil sands process affected water (OSPW). OSPW contains naphthenic acid fraction compounds (NAFCs) which have been found to contribute extensively to OSPW toxicity. Degradation of this...

Boxed-in: Comparing Algorithms for Box-flight Mass-Balance Greenhouse Gas Flux Measurements from Mineable and In Situ Oil Sands Developments
DownloadSpring 2022
To combat global warming, Canada has committed to reducing greenhouse gases (GHGs) 40-45% below 2005 emission levels by 2025. Monitoring emissions and deriving accurate inventories are essential to reaching these goals. GHGs can be measured at a small scale, often using ground measurements which...

Fall 2013
The high degree of variability of oil sands ores can be attributed to a mixture of different geological end members, i.e., estuarine sand, estuarine clay, marine sand and marine clay. This study focused on the mineralogy, especially of clay minerals, and toluene insoluble organic matter, referred...

Characterization of Clay Minerals in the Athabasca Oil Sands in Water Extraction and Nonaqueous Solvent Extraction Processes
DownloadFall 2011
Production of oil from the second largest oil deposit in the world, i.e., the Alberta oil sands containing approximately 13% of total proven oil reserves in the world (169.9 billion barrels), has been shown to be significantly influenced by clay minerals. Clay minerals in particular play a key...
