Environmental effects on the application of spring load restrictions on low volume roads in Northern Ontario / by Jeffrey Chapin.
(2010)Many jurisdictions throughout Canada and the United States utilize Spring Load Restriction (SLRs) on low volume roads to minimize the damage during spring thaw. The main objective of this research is to develop a SLR method ... -
Enzymatic hydrolysis of primary paper mill sludge and fermentative production of microbial lipids
(2018)Canada is known for its abundant forests and thriving forest products industry. For every ton of paper produced in mills across the country, approximately 30 kg of dry primary sludge is produced. The dry sludge is then ... -
Evaluation of GaN and InGaN semiconductors as potentiometric anion selective electrodes
(2006)Ion selective electrodes (ISEs) are chemical sensors primarily used for in situ analysis and monitoring of air, water, and land. Despite their easy fabrication, low cost, and simple usage, ISEs still suffer from the ... -
Experimental and theoretical studies on microalgal cell adhesion and interactions on membranes
(2021)Microalgae Cell adhesion is global and plays a critical role in different scientific and engineering problems especially in wastewater treatment. This study focused on both experimental and theoretical studies on microalgal ... -
Experimental Study of Vertical and Oblique Particle Clouds in Water
(2016)Sand jets and particle clouds are common in many engineering areas such as marine bed capping, dredging, and artificial island construction. Because of the wide range of their application, a better understanding of particle ... -
Experimental study on mixing of activated sludge with or without air in a mixing tank through electrical resistance tomography (ERT) and response surface methodology
(2017)In such industrial processes as oxidation, hydrogenation, and biological fermentation gas and liquid are contacted and mixed to reach steady condition. The unit operations applied for gas/liquid processes include but are ... -
Fish biomonitoring in an industrial environment : the Toxicity Early Warning System (TEWS)
(2009)Industrial, agricultural and municipal effluent discharge into receiving waters continues to be a significant environmental problem. Currently, industrial effluent quality is assessed using chemical assays or by evaluating ... -
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 ... -
Hydraulic and dynamic assessment of triangular labyrinth weirs and wier-pool type fishways
(2019)The hydraulic performance of traditional labyrinth weirs has been extensively studied in the literature. The research outcomes indicated that labyrinth weirs have many hydraulic advantages to pass more flow with a constant ... -
The influence of temperature on dynamic membrane structure
(2022)This study investigates the influences of cold source-water temperatures and warm temperature recoveries on the dynamic changes of membrane structure. The morphology of membrane pores on the membrane surface was firstly ... -
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 ... -
Investigation on liquid-liquid dispersion in stirred tanks through experimental approach and computational fluid dynamic (CFD)
(2019)Stirred tanks have a vital role in chemical engineering industries. Among the various applications of stirred tanks, mixing of two immiscible liquid phases is of interest in chemical processes. Mixing of two immiscible ... -
Lignin acrylic acid polymer as an emulsifier for oil-water emulsions
(2022)Oil-water emulsions are applied in various fields such as food, cosmetics, pharmaceuticals, petrochemicals, and agricultural products. Currently, synthetic-based emulsifiers are extensively used in oil-water emulsions, ... -
Lignin-based hydrogels
(2017)Currently, limited information is available on lignin-based hydrogels, but its potential in commercial applications presents a promising avenue for the utilization of lignocellulosic materials. Recent studies have employed ... -
Membrane fouling and its control in drinking water membrane filtration process
(2014-01-22)Treatment of surface water in the presence of natural organic matters (NOM) becomes a challenging issue to meet stringent rules of Safe Drinking Water Act (SDWA). Ultrafiltration (UF) membrane is emerging as an efficient ... -
Mesophilic submerged anaerobic membrane bioreactor for pulp and paper secondary sludge treatment
(2018)The production of pulp and paper is associated with the generation of large quantities of wastewater that has to be purified to avoid severe pollution of the environment. Wastewater purification in pulp and paper mills ... -
Microbial methylation of mercury in the North Harbour of Lake Superior
(2019)Mercury is a known contaminant in the North Harbour of Lake Superior due to the decommissioned “Thunder Bay Fine Papers” pulp and paper mill. The cause for concern for organisms in the lake and for humans occurs when ... -
Modeling groundwater flow and transport of contaminants at a former manufactured gas plant in the midwestern USA
