The presence of manganese in drinking water supplies has been problematic for drinking water providers as it can be difficult to remove during treatment and it creates aesthetic challenges, such as colored (e.g. black, brown) and bad tasting/smelling water. Recently, Health Canada has proposed a health-based maximum acceptable concentration for Mn of 0.10 mg/L. Biofiltration technology is growing in popularity as a sustainable method for removing Mn from drinking water; however, there is a lack of evidence to support the effectiveness in cold water (less than 10ºC).
Nitrogen and phosphorus are sources of eutrophication (e.g., blue-green algae bloom) in rivers and lakes. The bloom of blue-green algae can significantly affect aquatic lives and human activities because of the toxins that they produce. Therefore, it is crucial to reduce the nitrogen and phosphorous concentrations in municipal wastewater discharges. Conventional treatment techniques using activated sludge (AS) based biological nutrient removal (BNR) process often experiences system deficiency at low temperature (winter) and under increased hydraulic loads (e.g., snow melting events).
Intelligent Transportation System (ITS) enables smart traffic management and provides various innovative services including better safety, more road information, etc., which has drawn a lot of attention. The development of next-generation ITS services and applications must depend on more accurate positioning information at decimeter to even centimeter-level. Such capabilities are crucial because all of the innovative applications are based on the precise positioning of land vehicles.
Electrification of transit vehicles is a part of Ontarios long-term strategy to reduce transportation-related greenhouse gas (GHG) emissions. However, transit agencies and utility/local distribution companies face significant technological and operational hurdles in integrating off the shelf electric bus technologies. The postdoctoral fellow collaborating with Canadian Urban Transit Research & Innovation Consortium will work with transit agencies and utilities to overcome the technical challenges associated with a lack of international standardization for overhead charging systems.
The following research project will be used to investigate, develop and determine the performance of the application of a new nanotechnological material as a coating on glazing for the purposes of reducing the transmittance of specific wavelengths on the spectral curve. This will reduce the overall building heating and cooling energy consumption and will create a new market for the product in Canada and abroad.
Pollutants in stormwater runoff and municipal wastewater are grave concerns to the receiving environment of lakes and streams, as nutrients (Phosphorus (P), Nitrogen (N)) contribute to eutrophication. While rain gardens are effective to retain and retard stormwater runoff and removal of certain organic pollutants, limited studies have been conducted on nutrient capture.
This research focuses on waste-to-resource for nutrient removal from aqueous environments.
Substitution of existing diesel buses by zero-emission propulsion technologies (electric batteries and hydrogen fuel cell) in vehicles specifically public transit fleets can play an instrumental role in realizing Canada's obligation towards green house gas emission reduction. It is imperative to enable transit agencies to assess the capabilities of existing technology variants in meeting the demands of existing operations to achieve successful, long-term integration while maintaining commercially viability.
Cyanotoxins, produced by blooms of cyanobacteria, have been a cause of concern, as they have the potential to compromise animal and human health. Because of increased nutrient loading and climate change, occurrence of cyanobacterial harmful algal blooms and their toxins are increasing globally. The presence of these compounds in the Great Lakes and other water sources in Canada, the United States and worldwide, presents challenges for municipalities that are treating and distributing drinking water.
Riverbank erosion is a major threat to millions of Bangladeshi citizens who live in the vicinity of the countrys rivers, causing loss of life, land and livelihood. Sand-filled geotextile bags (geobags) are a solution to this problem and are widely used across Bangladesh to guide river flow and redirect channels in the wide braided rivers, preventing erosion and enabling land reclamation.
This research aims in utilizing agriculture wastes in production of sustainable eco-friendly construction materials for farms building. The mechanical and durability performance of the proposed eco-friendly construction material exposed to the aggressive agriculture environment will be evaluated. The research will investigate the effects of different factors mainly related to physical properties of used wastes and binding materials.
