A Combined Membrane Filtration - Aeration Approach for the Treatment of Hydraulic Fracturing - Flowback and Produced Water from the Duvernay FormationDownload
Membrane filtration technologies have been successfully applied for the treatment of many types of wastewater. In hydraulic fracturing operations, membrane processes can be applied as a cost-effective way of removing unwanted substances from flowback and produced water (FPW) and promoting its...
Application of SWAT-MODFLOW Software to Evaluate Groundwater-Surface Water Interaction in West-Central AlbertaDownload
Responsible watershed management is emerging as a key issue as humanity continues to place increasing demands on water resources. To meet future demands, it has become imperative that water resources be managed as a holistic system rather than solely focusing on individual aspects....
Banded iron formations (BIF) are a key chemical sedimentary record for examining the evolution of the early oceans, atmosphere, and biosphere. While the classic model suggests that BIF were deposited by either anoxygenic photoferrotrophs or oxygen producing cyanobacteria, recent studies have...
Biogeochemistry of meromictic pit lakes and permeable reactive barriers at the Cluff Lake uranium mineDownload
Mining generates not only vast amounts of waste rock and tailings but is also responsible for far-reaching contamination of soil, groundwater, and surface water, which often requires remediation. This thesis focused on the biogeochemistry of two types of remediation technologies applied at the...
Clay minerals are ubiquitous at the Earth’s surface and they impart a significant influence on numerous geochemical cycles due to their high surface reactivity. Aqueous pH and ionic strength (hereafter IS) are two major factors that affect clay surface reactivity and subsequently govern trace...
Effects of salinity on the leaching of ionic species from the Duvernay Formation, a Canadian hydraulic fracturing playDownload
Hydraulic fracturing combined with horizontal drilling has revolutionized the oil and gas industry in North America. The majority of Canada’s hydraulic fracturing operations are in Alberta and British Columbia, with the Montney and Duvernay formations ranked highest in five hydraulically...
Lithium Recovery from Hydraulic Fracturing Flowback and Produced Water using a Manganese-Based SorbentDownload
Increased demand for lithium products for use in lithium ion batteries has led to a search for new lithium resources in recent years in order to meet projected future consumption. One such potential lithium resource is low lithium bearing brines that are discharged from hydraulically fractured...
Biochar has received significant attention as an innovative sorbent for treating heavy metal contamination due to its high surface reactivity and sorption capacity, ease of manufacture and low production cost. Most studies involving chromium removal from solution by biochar have focused on...
Microbial Community Dynamics in the Hydraulic Fracturing Water Cycle from Two Newly Fractured Shale Gas Wells in the Duvernay Formation, AlbertaDownload
The microbial ecology of the hydraulic fracturing water cycle may influence the efficiency of shale gas production and strategies for water reuse and treatment. In this study, microbial community dynamics were tracked by sequencing of 16S rRNA genes coupled with enumeration of live/dead cells in...
Green rust (GR) is a group of mixed FeII and FeIII hydroxide minerals and is an important phase in both modern and ancient geochemical systems. For this reason, establishing the thermodynamic properties of GR is vital to understanding and modelling its role in natural systems. In this study,...
