Spring 2014
The objective of this study was to determine if there was any difference in the bioremediation of oil sands process-affected water (OSPW) and to quantify and identify bacteria present in different scenarios. Two reactors were compared in this study: an acetic acid amended OSPW bioreactor, (AAAO...

One of the current technologies used by the oil sands industry to reduce the volume of fluid fine tailings and create a dry landscape is production of CT (Composite Tailings) and NST (Non-Segregating Tailings). CT and NST are engineered tailings streams obtained by recombination of fines (MFT or...

A large amount of fluid fine tailings (FFT) is stored in tailings ponds and is continuously accumulating from the extraction of bitumen from oil sands ore in northern Alberta. The FFT are high in water content and have a very slow dewatering behavior that requires many years for them to fully...

Effect of Diluent Levels on Greenhouse Gases and Reduced Sulfur Compound Emissions from Oil Sands Tailings
DownloadSpring 2016
A well-known issue of tailings is that they have poor consolidation properties, which, in situ, may require several decades or more before the material can be reclaimed. With the accumulation of tailings in the tailings ponds, one unintended consequence of this long-term storage is the evolution...

This study investigated the mechanisms driving the dewatering and strength behaviour of polymer amended treated (centrifuged and in-line thickened tailings/ILTT) deep tailings deposits undergoing seasonal weathering dominated by a) multiple freeze-thaw cycles and b) alternating freeze-thaw and...

This research is an experimental, field and numerical study of the sedimentation and consolidation of in-line thickened oil sands fine tailings. In-line thickening is a process that adds flocculant and coagulant into a modified tailings pipeline in a multi stage fashion to improve the dewatering...

Hydrogen sulfide (H2S) is the primary cause of the widespread odor and corrosion issues in sanitary sewer systems. When wastewater falls in drop structures, the emission of H2S is expected to be significantly enhanced. This study focuses on the mass transfer coefficient, KL, for H2S and other...

ABSTRACT This research is an experimental design and numerical analysis of a novel technique of the vacuum consolidation of Mature Fine Tailings (MFT). A meso-scale test was conducted to examine the feasibility of the MFT dewatering process. Vacuum consolidation involves applying a negative...
