Evaluating the Metal Tolerance Capacity of Oil Sands Tailings Microbes, and their Ability to Degrade Naphthenic Acids While Attached to Biochar
Alberta’s oil sands process water (OSPW) was used herein as a case to investigate co-contaminated wastewater treatment; naphthenic acids (NAs, implicated for OSPW toxicity) and metals have been reported in OSPW. This thesis sought to evaluate the metal tolerances of a native OSPW microbial …

Removal of acid-extractable organics from oil sands process-affected water using carbon-based adsorbents
… water, called oil sands process-affected water (OSPW), is stored in tailings ponds. Acid-extractable organics (AEO), one of the components of OSPW, are believed to be the main component of toxicity in OSPW, and create harmful effects to aquatic organisms, mammals and birds. To discharge OSPW into …

Performance Characterization of Coagulation Pretreatment for Two Industrial Effluents
… remediation of oil sands process-affected water (OSPW), generated from oil sands operations in Alberta, Canada. OSPW is a complex mixture of suspended solids, various suspended and dissolved organic compounds. Alum and natural coagulant Opuntia ficus-indica (OFI) were used as the coagulants, and …

On the bicyclic acids of petroleum
… produced waters and oil sands process waters (OSPW), respectively. Understanding the toxicity, transformations during biodegradation and remediation treatments and predicting the fate of NA in the environment will be aided by the identification of individual NA. However the elucidation of …

Development of Novel High Temperature Mixed Matrix Membranes (MMMs) for Oil Sands Wastewater Treatment
… and reuse of oilsands process-affected water (OSPW) can be considered a strategical solution to addressing these issues. Membrane technology is a promising option for OSPW treatment due to its high removal efficiency, small footprint, facile operation, installation and scaleup. Mixed matrix …

Evaluation of the immobilized soil bioreactor for treatment of naphthenic acids in oil sands process waters
… barrel of crude oil. Oil sands process water (OSPW) contains naphthenic acids (NAs), a complex mixture of carboxylic acids of the form CnH2n+ZOx that are persistent and toxic to aquatic organisms. Previous studies have demonstrated that aerobic biodegradation reduces NA concentrations and OSPW …

The Influence of Water Quality Characteristics on Vanadium Toxicity to Model Aquatic Organisms
… used to treat oil sands process-affected water (OSPW) to reduce organic toxicants. However, PC contains up to 1,000 mg of V per kg of PC, and during OSPW treatment V leaches from coke reaching levels of up to 7 mg/L in “treated” OSPW, a concentration that is toxic to aquatic organisms. Little …

Biogeochemical investigation of centrifuged fine tailings deposits at an oil sands mine in Northern Alberta, Canada
… suspended in oil sands process-affected water (OSPW). High sodium (Na) concentrations in OSPW increase the electrical double layer (EDL) thickness at clay-mineral surfaces, which hinders aggregation and, therefore, settlement. Production of CFT involves dredging FFT from tailings ponds, amending …

Synthesis, Fractionation, Characterisation and Toxicity of Naphthenic Acids from Complex Mixtures
… concern in the oil sands process-affected water (OSPW) that has accumulated in vast quantities following exploitation of the oil sands of Northern Alberta, Canada in recent years. However, though there have been calls for NAs to be added to pollutant inventories, at the initiation of the current …

SEE. I AM ONE. BALANCING POWER IN GENOMICS RESEARCH OF CONSTRUCTED WETLANDS TO CLEAN OIL SANDS TAILINGS WATER
… (CTWS) to remediate oil sands processed water (OSPW), I was positioned to study the researchers, research, and community perspectives, to contribute to a gap on how these collaborations can increase their effectiveness in using multiple ways of knowing. My work proposed to even-out power …

Identifying water contamination from fossil fuel development using geochemical and isotopic fingerprints
… ratios of oil sands processed-affected water (OSPW). In three case studies, these geochemical and isotopic tools were integrated into comprehensive geochemical frameworks that investigated the (1) leaking of coal ash ponds to surface and groundwater in the southeastern United Sates; (2) …
