Integrated stochastic modeling of pharmaceuticals in sewage networks

Sylvain Coutu, Timothée Noé Pouchon, Pierre Claude Jean Queloz

Pharmaceuticals and particularly antibiotics can harm sensitive aquatic species. Their occurrence in urban wastewater systems is the consequence of five successive processes: (i) ingestion of the substance, (ii) accumulation in the urine, (iii) excretion, ...

Modelling the effect of fluctuating herbicide concentrations on algae growth

Sylvain Coutu, Pierre-Jean Copin

Herbicide concentrations fluctuate widely in watercourses after crop applications and rain events. The level of concentrations in pulses can exceed the water chronic quality criteria. In the present study, we proposed modelling the effects of successive pu ...

Substance flow analysis as a tool for mitigating the impact of pharmaceuticals on the aquatic system

Luca Rossi, Sylvain Coutu, Htet Kyi Wynn, Jonas Margot

Pharmaceuticals constitute an important environmental issue for receiving waters. A holistic approach, taking into consideration the sources of these compounds (hospitals, domestic use), discharges (wastewater effluent, combined sewer overflows) and relate ...

Temporal dynamics of antibiotics in wastewater treatment plant influent

David Andrew Barry, Luca Rossi, Sylvain Coutu, Htet Kyi Wynn, Vera Wyrsch

A yearlong field experimental campaign was conducted to reveal time scales over which antibiotic fluxes vary in the influent of a wastewater treatment plant (WTP). In particular, sampling was carried out to ascertain the amplitudes of monthly, daily and ho ...

A computational platform for integrated modelling of micropollution in the urban environment

David Andrew Barry, Luca Rossi, Sylvain Coutu, Timothée Noé Pouchon

Anthropogenic chemical contaminants are found routinely in our water resources. Although most of these compounds are usually present at low concentrations, they are of concern due to their ecotoxicity, antibacterial resistance and potential harm to human h ...

Model falsification diagnosis and sensor placement for leak detection in pressurized pipe networks

Ian Smith, Sylvain Coutu, James-Alexandre Goulet

Pressurized pipe networks used for fresh-water distribution can take advantage of recent advances in sensing technologies and data-interpretation to evaluate their performance. In this paper, a leak-detection and a sensor placement methodology are proposed ...

Impact of climate change on runoff pollution in urban environments

David Andrew Barry, Sylvain Coutu, Sébastien Kramer

Runoff from urban environments is generally contaminated. These contaminants mostly originate from road traffic and building envelopes. Facade envelopes generate lead, zinc and even biocides, which are used for facade protection. Road traffic produces part ...

Lessivage des polluants urbains et changement climatique : l’influence des modèles

David Andrew Barry, Luca Rossi, Sylvain Coutu, Sébastien Kramer

Rainfall for the next century will be influenced by global warming. These modified rainfalls will have influences on rainfall runoff. In order to analyze these impacts, this study compared different buildup and washoff functions with several future rainfal ...

Modelling wind-driven rain on buildings in urbanized area using 3-D GIS and LiDAR datasets

Luca Rossi, François Golay, Sylvain Coutu, Claudio Magalhaes Carneiro, Pauline Emery, Vera Wyrsch

This study investigated the distribution of the fraction of rainfall intercepted by the facades of buildings located in an urbanized area. We used the frequently used semi-empirical standard ISO-15927-3 to simulate Wind-Driven Rain on facades. The implemen ...
