Modelling groundwater flow and contaminant transport at a gold mine site in Northern Ontario
(2015-02-02)
The practices of mining and ore processing are used in many countries around the world to
extract and concentrate the valuable natural resources found within the rock bodies which
make up the earth’s crust. However, the ...
Electrochemical methods and membrane bioreactor approach for wastewater treatment and water quality assessment
(2014-01-22)
Severe water scarcity, high health standards, and strict disposal limits have necessitated the development of novel and robust strategies for wastewater remediation and water quality analysis at lower cost with reduced ...
Admixtures for use in geopolymers
(2012-11-10)
This study examined two novel approaches for the geopolymerisation of fly ash produced at thermoelectric power stations by combustion of coal. The first approach involved the use of cullet, a post-consumer glass waste, to ...
Pretreatment and conditioning of municipal wastewater secondary sludge using freezing and a combination of ultrasound and freezing
(2014-01-22)
With the cost of sludge management on the rise, the volume reduction of municipal wastewater sludge is becoming an increasingly important issue for wastewater treatment plants. Current research is focused on pretreatment ...
Sulfonation of kraft lignon to water soluble value added products
(2014-12-11)
Kraft lignin is water insoluble and has limited end-use applications. The main objective of this MSc studies was to rend kraft lignin water soluble, and various value-added products including dispersants and flocculants. ...
Comparison of methods to determine the carbonation depth in fly ash blended cement mortars
(2014-01-22)
Carbonation negatively affects the durability of steel-reinforced concrete structures by causing a decrease in pore solution pH, thus facilitating corrosion which eventually leads to cracking and spalling. Different ...
Integrated solar electrokinetic remediation of soil contaminated with copper
(2012-11-10)
Electrokinetic remediation is an emerging in-situ technology for cleaning contaminated soil. The contaminants are mobilized by passing a low-level direct current between a row of positively charged electrodes (anode) and ...
Chemical and electrochemical modification of kraft lignin to value-added products
(2012-11-10)
Lignin is one of the most abundant biopolymers on earth, constituting approximately 30% of the dry weight of softwoods and 20% of hardwoods. It is a renewable, non-toxic, commercially available and low cost natural resource ...
Modeling groundwater flow and transport of contaminants at a former manufactured gas plant in the midwestern USA
(2013-02-01)
The processes used to produce manufactured gas for heating, cooking and lighting purposes in North America from the early 1800s to the mid-1900s have generated by- products such as coal tar containing Monocyclic ...
Groundwater contamination prevention using an electrokinetic barrier-cobalt trapping
(2015-06-15)
The quality of groundwater in many regions around the world has been compromised due to pollution from anthropogenic activities such as deposition of solid wastes containing heavy metals in landfills, industrial spills and ...
