The main objective of this research is the feasibility assessment of bioremediation of petroleum contaminated soils for cold climate conditions. LLSRI as the industrial partner is interested to evaluate feasibility of conducting bioremediation through the cold season to extend its operation and generate more revenue.
Destructive effects of Green House Oas (OHO) emissions on the environment such as climate change and global warming are some oftoday's major concerns. According to the "Environmental Protection Agency" (EPA) U.S 2010, construction is the third highest source ofOHO emission between other industrial sections. Underground utility construction projects are considered as one of the major areas of the construction projects. Also Underground infrastructure is aging across North America; hence rehabilitation or new installation of pipelines and facilities has become inevitable.
Contamination of soils and groundwater with gasoline often results in the development of anaerobic zones. Benzene is particularly persistent under anaerobic conditions even in the enhanced anaerobic biodegradation (EAB) process. Degradation of benzene has been demonstrated under nitrate-reducing condition, and sulphate-reducing condition. However, information of dominant indigenous species within the microorganisms for degrading benzene is still limited.
Constructed wetland is a critical water infrastructure in major Canadian cities like the city of Edmonton, which treats wastewater including storm water by reducing the suspended solids and the related contaminants before entering into receiving waterbody. The design and evaluating the performance of a constructed wetland requires accurate prediction of flow fields and particle pollutants settling behaviours.
Meeting the growing energy demands in a sustainable fashion is one of the greatest challenges of this century. This projects aims to evaluate a promising renewable energy source: concentrated photovoltaics (CPV). The configuration developed by our partner promises to offer utility-scale solar power at competitive prices, making it a viable alternative. It is based on large steel and glass structures that focus the incident light to reach over 1000x concentration onto a large array of high performance triple junction photovoltaic cells.
Sediment build-up in stormwater management ponds decreases their overall capacity to hold water and reduces their efficiency, in terms of controlling pollution. For this reason, and in order to comply with government regulations, municipalities must remove the sediment periodically. Determining when maintenance is required is difficult because it depends on a number of factors, and the actual cost of sediment removal from a wet pond is difficult to predict.
To reduce the impact on natural resources and extend the lifetime of existing quarries, this research will attempt to reduce the large quantities of quarried rock that are currently wasted for simply not meeting current aggregate grading requirements in standard construction specifications, even though some of those wasted size fractions would improve the quality and sustainability of concrete. By optimizing aggregate particle packing, more workable and durable concretes can be produced while also reducing the carbon dioxide producing, and energy-intensive, cement content.
