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...

The oil sands landscape in northern Alberta is interspersed with large tailings ponds that hold wastewater from bitumen mining and extraction processes. Recent monitoring results indicate that annually many thousands of birds, mostly migrating waterfowl, land on the ponds associated with this...

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...

Genotoxicity and Mutagenicity of Extractable Organics from Oil Sands Process-Affected Water
DownloadFall 2015
Oil sands process-affected water (OSPW) is produced in the surface mining industry during the hot-water extraction of bitumen from oil-sands ore. Its acid extractable organic (AEO) fraction is known to be acutely toxic, but few studies have addressed its genotoxicity or mutagenicity. Here, the in...

Monitoring Macrophage Immune Gene Expression Profiles as an Early Indicator System for Examining the Bioactivity of Oil Sands Process Affected Waters
DownloadFall 2021
Oil sands process-affected waters (OSPW) are by-products of bitumen (i.e. oil) extraction from the oil sands located in northern Alberta. These large volumes of water are held in tailings ponds and cannot be released due to their potential toxic effects. Overall, tailings ponds and mining...

Non-linear reparameterization of complex models with applications to a microalgal heterotrophic fed-batch bioreactor
DownloadSpring 2010
Good process control is often critical for the economic viability of large-scale production of several commercial products. In this work, the production of biodiesel from microalgae is investigated. Successful implementation of a model-based control strategy requires the identification of a model...

The continuing use of crude oil and development of the oil industry have resulted in complex hydrocarbon mixtures becoming common environmental contaminants. These contaminants, such as oil sands process affected water (OSPW) and crude oil, are especially of concern in aquatic ecosystems. OSPW...

Yu, T., Zhu, L., Yu, M., Ulrich, A., Delgado Chavez, L.
The objectives of our research program were to: (1) study biological activities in oil sands mature fine tailings and oil sands process-affected water, (2) develop microbial biofilm seed to support engineered biological processes with enhancement measures, and (3) review available bioreactor...

Self-cycling fermentation (SCF) is an advanced, automated, semi-continuous fermentation strategy that is used to improve the volumetric productivity of bioproduction. Typically, a microbial culture is grown in a reactor and half the reactor contents are harvested once a limiting nutrient is...
