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 ... -
Advanced ultrafiltration technology for lignocelluloses recovery and purification from thermomechanical pulp (TMP) mills process waters
(2017)Process waters of thermomechanical pulp (TMP) mills contain a large valuable quantity of lignocellulosic materials that end up in the wastewater for biological treatment. In recent years, interest in utilizing such compounds ... -
Agglomeration, adsorption and polymerization of hydrolysate components
(2020)Biomass utilization has been drawn attention of governments and industries, as it is renewable resource. Pulp and paper industry depend on woody biomass utilization system to get multiple products. However, it is also ... -
Application of Biomass-based Fly Ash in the Pressate of a Thermomechanical Pulping Process
(2016)In the thermomechanical pulping (TMP) process wood chips are pretreated with steam prior to refining, and the resultant effluent (TMP pressate) is currently treated in the wastewater treatment facility of the pulp mill. ... -
Assessment of hydrological drought in Northern Ontario using standardized streamflow index
(2018)Momentum is gaining for the use of a Standardized Streamflow Index (SSI) for the assessment of hydrological drought, which is an extension of the well-established and popularly used meteorological drought ... -
Carbon bio-sequestration by anhydrase enzyme extracted from spinach (Spinacia oleracea)
(2018)Demand for sustainable and new technologies striving for sequestration of greenhouse gases, particularly carbon dioxide, is an area of considerable focus. In recent years there has been an increased interest in using an ... -
CFD Modeling of an activated sludge bubble column
(2017)The bubble columns are widely used in different industries such as wastewater treatment, chemical, petrochemical, and biochemical. The current design of the bubble columns including but not limited to the geometry and ... -
Characterization and utilization of fly ash derived from the co-combustion of biomass and coal as a mineral admixture for ordinary Portland cement
(2009)Co-firing coal with renewable/waste biomass for power generation can mitigate the atmospheric discharge of pollutants (e.g., SO2) and green-house gases. Wide-spread application of this technology is impeded, however, by ... -
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 ... -
Chemical de-polymerization for reuse of polyethylene terephthalate (PET) towards a circular economy
(2022)Sustainable and effective waste management is very important to address environmental pollution. This is especially the case for plastics as their inherent resistance to breakdown leads to their accumulation the environment. ... -
Co-firing of lignite with peat and white pine in a pilot scale bubbling fluidized bed air - emissions and feedstock reactivity
(2010)The increasing awareness of the environmental impact of fossil fuels (mainly coal) combustion, which leads to high levels of CO 2 , NO x , SO 2 , mercury and particulate emissions, has motivated research for potential ... -
Comparison between thermophilic and mesophilic membrane-aerated biofilm reactors- a modeling study
(2018)Membrane aerated biofilm reactor (MABR), as a novel biological waste treatment technology, has received much attention in recent years, due to its advantages, as compared to conventional biofilm. Considerable amount of ... -
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 ... -
Developing an experimental setup for Thunder Bay waste pollution control plant (WPCP) to evaluate UV lamp performance
(2019)An automated experimental setup was developed to measure the spectral irradiance of new low pressure (LP) ultraviolet lamp (UV). The experimental analysis was performed by the measurement of the UV intensity along the ... -
Effect of carbonation on leachability and compressive strength of cement-solidified and geopolymer-solidified synthetic metal wastes
(2012-11-10)Stabilization/solidification (s/s) is a well-established technique for treating a variety of metal-containing hazardous waste streams prior to land disposal. Solidification refers to the improvement of the physical ... -
Effect of water salinity on the hydro-mechanical behaviour of light backfill material
(2007)A series of one-dimensional compression tests was conducted to examine and compare the hydro-mechanical behaviour of light backfill (LBF) material, composed of 50% bentonite and 50% sand, in the presence of distilled water ... -
Effects of feed and operating conditions on the performance and membrane fouling of a submerged anaerobic membrane bioreactor
(2012)Anaerobic membrane bioreactors (AnMBRs) have been recognized as an effective method for enhanced wastewater treatment and re-use. However, the loss of the membrane performances due to membrane fouling remains a major ... -
Effects of process operating conditions on performance and membrane fouling in submerged anaerobic membrane bioreactors (AnMBRs)
(2016)Submerged anaerobic membrane bioreactor (SAnMBR) technology is becoming an attractive alternative for industrial wastewater treatment as it improves the biological process while allowing for the recovery of energy through ... -
