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...

Micron-size particle suspensions are very common in industrial processes such as mineral extraction and wastewater treatment. These particles are difficult to separate from the fluid media due to their size. The formation of aggregates increases the effective size of these particles, increasing...

A major challenge to any “solvent-based” bitumen extraction technology is the removal of suspended fine solids from the hydrocarbon medium (i.e. diluted bitumen). To address this problem, we examined how colloidal solids could be made to aggregate in a hydrocarbon medium and thus be separated by...

Poor settling of solids increases land requirement for tailings containment and imposes severe constraints on the water balance. Consequent to these considerations, the alternating current electrocoagulation (AC/EC) technique emerged as a candidate for enhancing the settling behaviour of...

In the development of a numerical model for the water cycle on Mars, adsorption of water vapour in the Martian regolith acts as a significant sink and retards the transport of mass. Adsorption on Mars cannot be studied directly, so a numerical model was created, and a diffusion sorption...

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...

Atomistic Approach towards Sodium Citrate Role on Surface Properties of Silica and Clay Minerals
DownloadFall 2022
The use of sodium citrate as a secondary processing aid in combination with caustic significantly improved bitumen recovery, specifically in poor oil sands ores. The role of sodium citrate on wettability alteration of solid surfaces, benefiting bitumen liberation as well as improving bitumen...

Interactions of finely dispersed abrasive particles in chemical mechanical planarization (CMP) slurries play a vital role in determining the polishing performance. In this study, coupled influence of hydrodynamic and colloidal interactions on the attachment of nanosized ceria (CeO2) particles to...

In oil sands extraction, the removal of heavy materials from a bitumen feed is often facilitated by solvent addition treatment processes. These processes mix solvent with bitumen feed to cause the precipitation of heavy products. The settling properties of these heavy products as they separate...
