Swan Lake (SL) is located in the City of Markham, Greater Toronto, Ontario. The lake's water is known for its stagnant nature having no major natural inlet and outlet freshwater flows and this makes it particularly susceptible to contaminant build-up which results in high levels of nutrients (total nitrogen and total phosphorus) and chloride. This has led to significant deterioration of the water quality of SL. In the last decade, a few short-term and long-term strategies have been implemented for lowering the levels of nutrients and chloride to the recommended levels. However, these efforts have not been effective due to the continuous loading and detection of high levels of nutrients and chloride, and are less efficient. The partner organization in this project is City of Markham (CM), Ontario, Canada. CM is looking for a newer research approach to further improve the water quality of SL. The proposed research work introduces a new filtration technology based on biochar for efficient and enhanced removal of nutrients and chloride from SL. This project will optimize the biochar filtration system parameters and also develop a lab-scale filter unit for testing with SL water to remove the targeted compounds. This research will develop a sustainable technology to restore the water quality of SL. Throughout this project, multidisciplinary training will be provided to all HQPs (1 postdoctoral fellow and 2 undergraduate interns) for developing research and professional skills. The project's intended outcomes will lead to potentially economical (low-cost filter technology), environmental (eco-friendly and sustainable solution) and societal benefits (clean water) to Canada and Canadians. This project will also help Canada to maintain its leadership role in clean water technology. The success of this work can lead to the expansion of biochar uses into the water sector, enhancing job opportunities and likewise provisioning clean and safe water for Canadians.
