Community Structure and Microbial Activity of Sulfate Reducing Bacteria in Wastewater Biofilms and Mature Fine Tailings Analyzed by Microsensors and Molecular Biology Techniques
DownloadSpring 2015
Sulfate reducing bacteria (SRB) play a significant role in complex microbial environments such as wastewater biofilms and mature fine tailings (MFT). A unique characteristic of these complex microbial environments is that stratified structure containing both oxic and anoxic zones could be formed;...

Determination of biokinetic parameters of wastewater biofilms from oxygen concentration profiles
DownloadFall 2011
The process of scale-up and rational optimization of biofilm processes for effective wastewater treatment and reuse require better understanding of the biokinetic behavior of microorganisms in the biofilms. At present, no fast and accurate methods exist for determining kinetic parameters for...

This research was conducted in a response to the dissolved oxygen (DO) decline in winter in the Athabasca River. Sediment oxygen demand (SOD) is considered as one of the major factors contributing to the DO decline in the Athabasca River. The SOD is influenced by physical phenomena, chemical...

Laboratory Study on the Hydraulic Performance of Bioretention for Stormwater Management in Cold Climates
DownloadSpring 2019
Bioretention has shown effective stormwater peak flow and volume reduction in warm and temperate climates. However, the applicability of bioretention for successful stormwater management in cold and semi-arid regions such as Edmonton is still not well understood. Four large bioretention columns...

Membrane aerated biofilms (MABs) have exhibited unique advantages over conventional biofilms for wastewater treatment. However, due to the limited available technology to probe the internal biofilms, the information for multiple microbial processes inside the MABs is quite inadequate. Microsensor...
