Environmental engineering

Human activity is proving to be increasingly harmful to the environment. However, engineers and other professionals can limit or reduce the negative impact caused by human activities on the air and water, and on biodiversity, wildlife and flora.

This program trains specialists in the development of clean technologies and the procedures, methods and tools for sustaining them in order to resolve environmental problems caused by human activity.

Students learn a systemic approach to resolving environmental problems and acquire advanced knowledge in the field of environmental engineering related to ecosystems, analysis techniques, purification and treatment technologies, and other areas.

Students also develop the skills necessary to do the following:

  • Analyze the technical, economic, social and environmental issues associated with complex situations;
  • Design solutions from a preventive, corrective or curative perspective;
  • Validate the compliance of the solution and its implementation with the requirements of industries, municipalities and government institutions;
  • Evaluate the long-term socio-economic and environmental impacts when choosing a solution.

An example of environmental engineering

Since the introduction of a moratorium on the use of chlorination to disinfect wastewater in the late 1980s, government authorities and researchers have been working to devise the best alternative solution. Professor Robert Hausler, an expert in environmental engineering and wastewater treatment, is one of these researchers.

Processes that have been studied include ozonation, which proved to be among the best solutions. In addition to eliminating viruses and bacteria from the water, the ozonation process eliminates the most persistent pharmaceutical products found in the environment and reduces the incidence of endocrine disruptors that can jeopardize the survival of species.

In fact, medications, cosmetic products and certain household cleaning items used by the public are present in sewers, and ultimately in the environment. Ozonation treatment provides a solution for disinfecting wastewater and reducing the toxicity of municipal effluents. After years of concerted effort, this purification process is now an effective solution from an environmental perspective, is economically viable, and is well received by the public.

The expertise developed by Professor Hausler and his colleagues in the field of ozonation and advanced oxidation processes has opened the door for other implementation projects and the introduction of related industrial activities.
