Xylo-oligosaccharides and virginiamycin differentially modulate gut microbial composition in chickens

Zhao, Xin, Pourabedin, Mohsen, Guan, Leluo
Background The emergence and spread of antibiotic resistance in pathogens have led to a restriction on the use of antibiotic growth promoters (AGPs) in animal feed in some countries. The potential negative after-effects of a ban on AGPs could be mitigated by improving animal intestinal health...

A large amount of fluid fine tailings (FFT) is stored in tailings ponds and is continuously accumulating from the extraction of bitumen from oil sands ore in northern Alberta. The FFT are high in water content and have a very slow dewatering behavior that requires many years for them to fully...

Cationic and Anionic Dual Polymer Pairs for Mature Fine Tailings Flocculation and Dewatering
DownloadSpring 2016
The accumulation of oil sands tailings poses serious environmental issues in Alberta, Canada. In the tailings ponds, the fine clays and residual bitumen form the so-called mature fine tailings (MFT) which contain 30~40 wt% fine solid particles primarily below 44 µm in size, 1~3 wt% residual...

Surface mining for bitumen extraction results in production of tailings that are deposited into large ponds. Tailings in the ponds support diverse microbial communities capable of metabolizing organic compounds and producing biogenic gases (methane, CH4 and carbon dioxide, CO2). Because of low...

This research aims to assist in the assessment of tailings management technologies through the development of a dynamic simulation model. The developed model (TMSim) incorporates the mine plan, various stages of dewatering including classification, pre- and post-deposition dewatering, and an...

In bitumen recovery from oil sands, a percentage of the bitumen is lost to tailings. The effect of fugitive bitumen on fines settling and consolidation in tailings ponds remains controversial. In the current study, the settling performance of mature fine tailings (MFT) in response to flocculant...

Morphological Effects of Water Soluble Polymer Flocculants Synthesized by Controlled Reversible-Deactivation Radical Polymerization for Treatment of Mature Fine Tailings
DownloadFall 2020
The bitumen reserves in Northern Alberta are a valuable asset, but extracting bitumen from oil sands via the Clark hot water process produces undesirable waste tailings. These tailings are transported to tailings ponds where the sand and clay particles are left to settle slowly, creating a...

The by-product slurry resulting from the bitumen extraction process from oil sands sources, known as tailings, holds substantial amount of water along with clays and fugitive bitumen. Current polymer-based dewatering technologies are centred on acrylamide-based polymers such as polyacrylamide...

Application of Ozone and Peroxone Processes for Naphthenic Acids Degradation in Oil Sands Process-Affected Water: Characterization of Water Before and After Treatment
DownloadFall 2017
Appling ozone (O3) with high doses (>100 mg/L) to remove naphthenic acids (NAs) from oil sands process-affected water (OSPW); limits its application and feasibility in the OSPW remediation. To decrease the required doses and their associated costs, this study examined the application of ozone...

Development and application of Fenton and UV-Fenton processes at natural pH using chelating agents for the treatment of oil sands process-affected water
DownloadFall 2016
The increasing amount of oil sands process-affected water (OSPW), its high toxicity towards aquatic organisms due to naphthenic acids (NAs) and other organics, and the zero discharge practice of the oil sands industry urge researchers to seek effective approaches for its treatment. Advanced...
