Removal of acid-extractable organics from oil sands process-affected water using carbon-based adsorbents
In surface mining process, 1.9 volumes of freshwater are used for each volume of bitumen produced and the used 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 …

Performance Characterization of Coagulation Pretreatment for Two Industrial Effluents
… adsorption were applied for the 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) …

Biogeochemical investigation of centrifuged fine tailings deposits at an oil sands mine in Northern Alberta, Canada
… fine tailings (FFT) stored in tailings ponds at oil sands mines. Increasing FFT inventories in tailings ponds results from slow settlement of clay minerals suspended in oil sands process-affected water (OSPW). High sodium (Na) concentrations in OSPW increase the electrical double layer (EDL) …

The Influence of Water Quality Characteristics on Vanadium Toxicity to Model Aquatic Organisms
… contaminant of emerging concern for the Alberta oil sands region that could present a risk for aquatic organisms. Petroleum coke (PC) has been experimentally 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, …

Identifying water contamination from fossil fuel development using geochemical and isotopic fingerprints
… about the risks fossil fuel development pose to water resources. Previous studies have identified negative impacts on water quality associated with the storage and disposal of coal combustion residuals, oil sands process-affected water, and oil and gas wastewater, as well as leaking of methane to …

Synthesis, Fractionation, Characterisation and Toxicity of Naphthenic Acids from Complex Mixtures
… occurring in unrefined and refined crude oils and the associated polluted production waters, complex mixtures of acids, known historically as naphthenic acids (NAs), have achieved prominence. This is particularly because NAs have been designated a toxicant class of concern in the oil sands …
