An Investigation of Potential Weed Management Practices and Multivariate Assessment Parameters for Alberta's Oil Sands Reclamation Efforts
DownloadSpring 2018
Reclamation efforts that promote the re-establishment of native tree and plant communities subsequent of large-scale oil sands mining land disturbances are crucial in restoring natural ecosystems. It is important that reclamation procedures capable of facilitating the establishment of native...

Application of coagulation-flocculation process for treating oil sands process-affected water
DownloadFall 2011
Oil Sands Process-Affected Water (OSPW) is generated from oil sands operation processes such as mining, extraction, and upgrading. Currently, accumulated OSPW is temporarily stored in tailings ponds which are toxic to the environment and must be treated for either reuse or safe discharge in the...

Application of Coagulation/Flocculation followed by Sedimentation for Treating Urban Combined Sewer Overflows
DownloadFall 2017
Combined Sewer Systems are commonplace in the United States and the major cities in Canada. These systems consist of both sanitary and stormwater lines which, when combined, create the potential for large surges of wastewater during storm conditions known as Combined Sewer Overflows (CSOs). CSOs...

Spring 2015
A multi-purpose settling column was designed to determine settling rate and sediment height allowing the in-situ measurement of yield stress and drainage without disturbing the sediment particle network. The settling column was applied to studying flocculation/densification of model oil sands...

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...

Automating Information Flow in Hyperspectral Measurements for Soil Characterization in Tailings
DownloadFall 2015
In the first section of this thesis, two laboratory experiments conducted on tailing samples were evaluated using a structured qualitative analysis procedure. The process model of Suppliers, Inputs, Process, Output, and Customers (SIPOC) was used to study relationships amongst different parts of...

Biodegradation of Hydrocarbons in Bitumen: Exploring Plant-Assisted and Microbial Stimulation Techniques
DownloadFall 2020
While bitumen is one of the oldest construction materials in the world and currently provides an important fuel needed to sustain our modern lifestyle, the disturbances caused by extracting and refining this material are considerable, with 895 km2 of land being disturbed in Alberta as of 2018...

Spring 2024
Hydrolyzed polyacrylamide (HPAM) is a common flocculant used in oil sands tailings dewatering technologies. Although HPAM is regularly used in tailings treatment and will eventually be incorporated into the reclaimed landscape of the oil sands, there are knowledge gaps surrounding the environment...

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...

Challenges of utilizing municipal compost as an amendment in boreal forest reclamation subsoil material
DownloadFall 2018
Forest reclamation sites are often located in areas not suited for agriculture and therefore have poor soil conditions. To assist in the rehabilitation of forests on these types of sites, organic amendments can be used. Close to large urban centers, compost derived from municipal organic waste...
