Title: On thin ice: Are lakes feeling the heat?
Abstract: Lakes are warming around the world in response to a changing climate, including warmer water temperatures and shorter ice duration.  Lake ice is at risk of becoming extinct in thousands of lakes around the Northern Hemisphere with widespread consequences for ice fishing, recreation, and transportation. Historically Canadian lakes have been highly significant bellwethers, as they represent a northern or southern limit to many freshwater fish species.  This makes Canadian fishes particularly vulnerable to climate change.  Of particular interest are walleye and smallmouth bass.  Walleye, trout, and smallmouth bass are all angler favourites.  But as the feisty smallmouth bass continues its march northward in Canada, it will put populations of trout and walleye at long-term risk.

Title: Moving Conventional WasteWater Treatment Plants (WWTPs) into Water Resources Recovery Facilities (WRRFs)
Abstract: The future vision for wastewater treatment plants (WWTPs) is to no longer consider these facilities as an activity for removing pollutants but a facility that can couple the treatment process with the generation of value-added products, which are known as water resources recovery facilities (WRRFs). However, the definition of the WRRF is still ambiguous and various applications are under research to define different strategies to upgrade the WWTPs into WRRFs.
Different Biotechnologies can be integrated to play a key role in the development of WRRFs. In this seminar, I will share with the audience three main objectives were set to evaluate the possibility of integrating two promising Biotechnologies within WRRFs. The primary focus of this talk is to provide a high-level overview of the next generation of wastewater treatment plants using biofilm processes and their integration to maximize energy and value-added products recovery, including biomethane, biohydrogen, and biopower, in accordance with the emerging paradigm shift towards mining resources from wastewater.
The need of reducing power consumption and carbon footprint for wastewater treatment plant is driving this technology development. The new generation of such Bioprocesses will include the application of sustainable novel biological reactors coupled with the recovery of the value-added products and energy that are generated in such a process, as well as the use of energy efficient processes to transform “energy-consuming treatment processes” into “energy-saving and energy–positive systems”.
