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 ...
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. ...
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 ...
Pretreatment and enzymatic hydrolysis of peat and pine sawdust for bio-ethanol production / by Wei Shi.
(2010)
This thesis includes three parts: 1.) effect of hydrogen peroxide on delignification of peat; 2.) pre-treatment of pine sawdust using various methods, including organosolv extraction, ultrasonic treatment, and sodium ...
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 ...
Validation of discrete ordinate radiation model for application in UV air disinfection modeling
(2014)
This study investigated one of the most important aspect of ultra-violet (UV) air disinfection modeling which is radiation modeling. Radiation modeling is a topic of interest in the domain of UV air disinfection research. ...
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 ...
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 ...
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 ...
A novel approach to reaction modeling for photocatalytic oxidation processes
(2014)
Volatile organic compounds (VOCs) are one of the major concerns for indoor air quality. A new
method for treating VOCs in the air is through an advance oxidation process (AOP) known as
photocatalytic oxidation (PCO). ...
