Standard Operating Procedures for Analysis of Naphthenic Acids from Oil Sands Process-Affected Water
Download2014-12-08
Mahdavi, H., Hepperle, S., Burkus, Z., Mian, H.
Naphthenic acids (NAs) are considered the main source of chronic and acute toxicity in oil sands process-affected water (OSPW). The purpose of this investigation is to establish elements of a standard procedure to determine and minimize the amount of NA loss during storage, sample preparation...

Application of Forward Osmosis Membrane Technology for Oil Sands Process-Affected Water Desalination
Download2014-10-01
The extraction process used to obtain bitumen from the oil sands produces large volumes of oil sands process-affected water (OSPW). As a newly emerging desalination technology, forward osmosis (FO) has shown great promise in saving electrical power requirements, increasing water recovery, and...

Microcosm Evaluation of Community Level Physiological Profiling in Oil Sands Process Affected Water
Download2012-11-02
Eaton, B., Humphries, D., Davies, J.
A microcosm-based experiment was conducted to investigate the ability of community level physiological profiling (CLPP) to detect changes in an aquatic microbial community resulting from exposure to oil sands process affected water (OSPW). Detection of the microbial response was done by using...

Designer Biochar-Coke Mixtures to Remove Naphthenic Acids from Oil Sands Process-Affected Water (OSPW)
Download2014-11-27
Alessi, D.S., Alam, M S., Kohler, M.C.
The objective of this 6-month pilot experimental study was to test the ability of biochars derived from Alberta biomass and an oil sands petroleum coke to remove selected organic acids from water. To this end, we selected one biochar produced from wheat straw and made by the Alberta Biochar...

Belosevic, M., Singh, A., Gamal El-Din, M., Li, C., McPhedran, K., Chelme-Ayala, P., Klamerth, N.
Large volumes of oil sands process-affected water (OSPW) are produced by the surface-mining oil sands industry in Alberta. The industry is following a no-release practice for OSPW due to its potential environmental toxicity. Both laboratory and field studies have demonstrated that OSPW is toxic...

Benign-by-Design: Synthesis of Engineered Silicon Nanoparticles and their Application to Oil Sands Water Contaminant Remediation
Download2013-11-29
Iqbal, M., Veinot, J.G.C., Purkait, T.K., Goss, G.G.
Oil sands are naturally occurring mixtures of sand or clay, water, fine silts, and bitumen. The oil sands extraction process consumes large volumes of water (i.e., ca. 3 barrels of fresh water for every 1 barrel of oil). Following the extraction of bitumen from the oil sands, a tailings slurry...
