Peter Vanrolleghem

Professor and Canada Research Chair on Water Quality Modeling, Université Laval

Peter Vanrolleghem is a bio-engineer from Ghent University (Belgium), where he specialized in industrial microbiology. His PhD from the same university was a modelling methodology study for wastewater treatment. After 9 years as a professor at this university, dealing with a variety of bioprocess modelling studies, he immigrated to Canada in 2006 as holder of the Canada Research Chair in Water Quality Modelling. Most of his research has focused on the monitoring and modelling of water quality in the integrated urban wastewater system, starting from the drop coming out of a cloud or the tap, traveling through storm and combined sewer systems and the water resource recovery facility, until the impacts on lakes and rivers. Starting in the mid-90s, he been particularly interested in modelling and predicting the fate of (down-the-drain) chemicals of emerging concern and pollution associated with suspended solids.

As a modelling methodology expert with considerable field study experience, he has insights in experimental design, setting up measurement campaigns, installing sensors and data treatment methods in view of high quality modelling. The new models he develops are so-called phenomenological: they are based on bio-physicochemical mechanisms, but don’t go into the full details so as to make them manageable in terms of data needs, and keep them focused on solving the problem at hand.

In terms of the COVID-19 wastewater-based epidemiology, it is worth mentioning that Peter has collaborated with Christoph Ort (Eawag) on the back-calculation issues due to in-sewer biodegradation of a variety of drugs (ES&T, 50, 13351). He also has a good understanding of measurement and modelling uncertainties in decision-making. With the Danish Technical University, an extensive model library was developed for dynamic priority pollutant fate throughout the overall wastewater system. This model library covers most processes that may affect the fate of SARS-CoV-2 as it travels through the sewer system.
