Onsite Domestic Wastewater Treatment and Reuse is emerging as a potential solution to the water shortages, eroding distribution infrastructure, and energy intensive treatment processes that are a fixture of the modern city. However, existing onsite treatment technologies fail to compactly treat water to a high enough quality for urban reuse without increasing per capita treatment energy use.
The proposed research project aims to optimize the conditions for Carbon dioxide eXpanded Liquid Extraction (CXLE) which uses liquefied Carbon Dioxide (CO2) and ethanol as co-solvents for extraction of compounds from natural sources. Design alterations will be implemented to a Supercritical Fluid Extraction (SFE) unit at the partner organization (BioFoodTech) to perform CXLE and further increase the extraction amount as well as extraction rate.
Copper and palladium (Cu-Pd) mineralization at the Marathon Deposit are associated with gabbro rocks. It is fundamentally important to be able to distinguish among the different types of gabbros, because only those of the Marathon Series are host to mineralization. This is accomplished through logging drill core, whole rock geochemistry and mineralogy.
Sudbury represents the site of a meteorite impact structure originally greater than 200 km in diameter and that formed 1.85 billion years ago. Despite the proven and potential economic benefits of resource development at Sudbury, there are still major outstanding questions concerning our understanding of the structure and its ore deposits. A series of objectives have been composed concerning the origin of Sudbury Breccia, host to footwall vein deposits, and Offset Dykes at the Post Creek locality and their mineralization.
Harmful bacteria in drinking water can be a great threat to humans, causing diseases and possibly death. This project is aimed at determining the safety of drinking water for consumers, especially in communities where access to sophisticated laboratory facilities is limited. This research project will help to further develop a portable bacteria sensor for water, capable of determining the presence of harmful bacteria in water. The technology will offer faster analysis than the typical 1-2 day water analysis for bacteria.
Several studies have shown that water levels of the Great Lakes would inevitably decline in a warmer climate. These studies were based on a modeling system that was not accounting for two-way exchanges of water and energy between the atmosphere and the earth surface, hence excluding key feedback mechanisms. The general objective of this project is to improve our understanding of the Great Lakes water resources and its sensitivity to climate change.
Safe drinking water supply is a daily need but it can be seriously threatened by microbial hazards originating from fecal contamination of source water, especially following periods of intense rainfall. In order to assess drinking water intakes (DWIs) vulnerability to fecal pollution and to take cost-effective decisions in case of hazardous events, it is urgent to implement early-warning systems. A recent enzyme-based technology, ColiMinder® enables to measure E. coli in water at high temporal resolution (every 30 minutes).
Dams can be problematic for fishes, particularly those that migrate. In order to help fish move around dams, fisheries managers may construct fishways (aka âfish laddersâ). However, these structures do not always function properly, often because they were built only to pass trout and salmon and are thus inappropriate for other species. This project aims to assess the ability of migratory rainbow smelt to use a newly constructed, âfish friendlyâ fishway at MacLeanâs Pond on the Vernon River, PEI.
In order to understand the movement of water in all its three phases on, under, and above the ground, scientists known as hydrologists use computer models. These models simulate the volume of water that runs through river in response to the amount of rainfall that has reached the ground during a specific time period. Hydrologists typically use weather stations to learn how much rain has fallen over the land. In Canada and in remote parts of the country, there are not many weather stations available.
Marine protected areas (MPAs) are a popular strategy for ocean conservation in Canada and several
options are available to pursue this type of protection. However, the current federal and provincial processes for
MPA development involve engagement in lengthy multi-stakeholder processes that can overwhelm local
communities and their conservation objectives. An alternative strategy is the establishment of MPAs led by
individuals or organizations in a community.
