Biosolids: Finding the right fit for your municipality 

ploughed field

Municipalities are looking for ways to recover valuable nutrients and generate energy within their wastewater systems. However, there is no one-solution-fits-all approach; local conditions, provincial regulations and social license are some of the variables that must be considered. This webinar looked at best practices in evaluating and developing various biosolids management options, as well as effective strategies for community engagement. 

About the Speakers

Trevor Brown manages the Region of Waterloo’s engineering and wastewater programs. His group is responsible for administering their wastewater treatment facilities’ operations and maintenance contract with Ontario Clean Water Agency, while also supporting capital projects relating to wastewater infrastructure renewal. Trevor also supports updates to the Region’s Wastewater and Biosolids Master Plan. Prior to joining the Region in 2008, Trevor held various engineering roles within the private sector. He holds a bachelor of applied science and master of applied science in environmental engineering from the University of Waterloo.

Conrad Allain is director of technical services for the Greater Moncton Wastewater Commission and is responsible for the planning and implementation of new projects, as well as upgrading existing assets to new standards. Mr. Allain was director of operations for the Commission for over 15 years and was on the design team during construction of Greater Moncton’s wastewater collection and treatment system. He played a key role in implementing a biosolids management program and managed the design and construction of a biosolids composting facility which features low manpower and energy use, efficient odor control and a unique compost heat recovery system. 


Opportunities for improved nutrient removal and recovery from municipal wastewater

Jan Oleszkiewicz webinar

Leading Canadian researchers discussed findings from a thorough review — commissioned by Canadian Water Network, on the current research, practice and regulations related to nutrient removal, recovery and reuse in Canadian municipal wastewater treatment, including: 

  • Nutrient removal practices and developing trends
  • Nutrient recovery and reuse practices and developing trends

  • Opportunities for improvement of Canadian wastewater treatment systems
  • Emerging issues and research gaps

About the Speakers

Dr. Jan Oleszkiewicz is a Distinguished Professor of Environmental Engineering at the University of Manitoba. He has published 500 papers and several books, and worked as an international consultant and advisor to several international corporations on design and implementation of nutrient removal and recovery and biosolids management for over 30 years. Jan is Vice-President – Western Region of the Canadian Association on Water Quality and active in International Water Association (IWA) where he chaired the Nutrient Removal and Recovery group.  He is presently involved in master plan activities for wastewater and bio-solids infrastructure in Canada and the USA.    

Damian Kruk has been involved in research on nutrient removal and recovery, developing a mainstream anammox process as well as process for simultaneous nitrification and electrokinetic phosphorus precipitation and recovery. He has expertise in plant process modeling and troubleshooting and rerating of biological nutrient removal facilities.

Tanner Devlin has been conducting research on aerobic granular sludge in batch and continuous process configurations. He has expertise in electrokinetic phosphorus removal from wastewater and was involved in developing technologies for nutrient removal from cold effluents. He has experience with treatment of industrial wastewater and removal of nanomaterials in biological processes.

Changing climate, watershed disturbance and potential risks to municipal waterworks systems in Canada

Wildfires webinar

Dr. Uldis Silins, University of Alberta
Dr. Monica Emelko, University of Waterloo
Dr. Mike Stone, University of Waterloo

Leading Canadian researchers discussed findings from their research — commissioned by Canadian Water Network, about how extreme events like fire and flooding related to climate change affect watersheds and drinking water systems, including:

  • Threats posed by extreme events to water supplies
  • Implications of climate-associated watershed disturbances for water treatment systems
  • Evaluating the trade-offs between source water protection and more treatment

About the Speakers

Dr. Uldis Silins is a professor of forest hydrology at the University of Alberta, where his research over the past two decades has focused on impacts of natural (i.e., wildfire and Mountain Pine Beetle) and human disturbance (i.e., forestry operations) on hydrology, water quality and aquatic ecology of forested source waters.

Dr. Monica Emelko is an associate professor of civil and environmental engineering at the University of Waterloo. Her research interests are focused on drinking water supply and treatment, particularly as related to sustainable technology design and optimization, risk analysis, integrated resource management, climate change impacts on water, groundwater under the influence of surface water, and quantitative microbial risk assessment.

Dr. Mike Stone is a professor in geography and environmental management at the University of Waterloo. His research is focused on land use change and its impact on surface water quality in natural and built environments. The goal of his research is to quantify and model the source, transport and fate of sediment-associated contaminants in aquatic environments to provide evidence-based science for policy development and environmental management. 


What are the potential risks of applying municipal biosolids to agricultural land?

McCarthy webinar

Dr. Jorge Loyo, Ryerson University
Dr. Lynda McCarthy, Ryerson University (Project Leader)

Dr. Loyo discussed findings from a literature review — commissioned by Canadian Water Network, on the current knowledge on the occurrence, fate and potential risks of emerging substances of concern (ESOCs) and pathogens in biosolids following land application, including:

  • Concentration and viability of ESOCs and pathogens following sludge treatment
  • Fate of ESOCs and pathogens in soils after biosolids application
  • Biological impact studies and risk assessment
  • Public acceptance of biosolids land application

About the Speaker

Dr. Jorge Loyo studied the fate, transport and effects of ESOCs as a postdoctoral scholar at Ryerson University and the University of California – Berkeley, and as an Assistant Professor at the Monterrey Institute of Technology and Higher Education in Mexico. Jorge holds a PhD in Environmental Engineering from the University of Maryland – College Park, and a BSc in Food Chemistry from the National University of Mexico. He currently lives in Houston, Texas.
