Globally and across Canada cities are challenged in providing sustainable water, and sanitation services are in the face of increasing water demand due to increasing life quality, decreasing water availability, more stringent water quality goals. Sustainable solutions considering energy and nutrient recovery are becoming an urgent demand. One option that improves upon economic, environmental and […]

Ce projet concerne le développement de nouvelles technologies de traitement de l’eau usée, en particulier celles pour l’enlèvement du phosphore. Récemment, la compagnie québécois Bionest a développé une no technologie de traitement à base de filtres à scories, qui sont un résidu de l’industrie de l’acier. La technologie est efficace pour enlever le phosphore et […]

A micro-algae bioreactor or photobioreactor can be used for cultivating micro-algae for the purpose to fix C02 or produce useable and commercial by-products. Specifically, micro-algae bioreactors can be used to produce fuels such as biodiesel and bioethanol, as a replacement to conventional fuel sources. The production of these biofuels also reduces greenhouse gasses as part […]

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 […]

Low impact development (LID) technologies are increasingly part of the urban landscape for Canadian municipalities. Bioretention planters, also known as rain gardens, are an LID technology that infiltrates and filters runoff at the source. Though design guidance exists, there is little data available on the long term performance of LID technologies, such as bioretention systems. […]

Les rejets de certaines mines en exploitation peuvent représenter un risque pour l’environnement. Les compagnies minières doivent se soumettre à différentes directives environnementales imposant une limite à la quantité de polluants rejetés dans leurs effluents. L’arsenic (As) est l’un de ces polluants. Il est libéré lors de l’extraction de divers métaux ayant une valeur commerciale. […]

La pêche sportive au saumon Atlantique est une importante industrie dans l’est du pays. Ce projet contribuera à améliorer une méthode de modélisation de l’habitat du saumon Atlantique, plus particulièrement en ce qui a trait aux nourriceries des tacons (saumons juvéniles). Les modèles d’habitat sont des outils mathématiques permettant d’évaluer quantitativement la quantité de l’habitat […]

Biofilms, surface-adherent microbial populations with enhanced tolerance to antibiotics and disinfectants, are widely-known contamination sources in environmental, industrial and medical settings. Novel approaches for the prevention and remediation of biofilms using nontoxic materials are urgently required. Interestingly, natural polysaccharides and nanopowders have anti-biofilm properties. We will develop a sustainable anti-biofilm technology using PhytoSpherix™ (Mirexus), a […]

Reservoir operators typically determine flow releases by assessing the available storage and demand and then applying a rule?of?thumb. Thus, in spite of numerous previous and current computer modelling studies, the use of computer models in real?time reservoir operation on a district level is virtually nonexistent. The resulting “water savings” offer the opportunity to increase river […]

The Canadian government has increased its focus on regulating wastewater to the environment. The advent of new regulations has resulted in many municipalities requiring substantial upgrades to minimize release of nutrients promoting eutrophic water bodies. Traditional wastewater treatment technologies are in some cases cost prohibitive. Bishop Water Technologies (BWT) provides an ecofriendly and cost-effective technology […]

Le lac Saint-Charles, principale source d’eau potable de la ville de Québec, a connu un vieillissement accéléré au cours des dernières années, en raison des plantes aquatiques et des sédiments qui le comblent graduellement. Cette situation est en bonne partie due à une surabondance d’azote et de phosphore dans un milieu où la rareté de […]

In warm climates warm temperatures cause thermal stratification in hydropower reservoirs inhibiting mixing and leading to deoxygenation of waters at depth (hypolimnium). Turbines withdrawing water at depth result in low dissolved oxygen (DO) in the downstream flow having a large negative impact on the downstream riverine ecosystem. Legislation in the USA and elsewhere now requires […]
