Behavior of NDMA precursors at 21 full-scale water treatment facilities

A source-to-tap evaluation of the origin and fate of chloramination N-nitrosodimethylamine (NDMA) precursors at 21 full-scale drinking water plants was conducted. Upstream wastewater discharges accounted for (on a median basis) similar to 16 ng L-1 NDMA fo ...

Quelle toxicité pour les plastiques récoltés sur nos plages ?

Luiz Felippe De Alencastro, Florian Faure, Frédéric Sciacca

Les débris plastiques accumulés dans l’océan mondial représentent une quantité considérable de plusieurs dizaines de millions de tonnes. Les microplastiques sont de minuscules fragments de plastique de diamètre compris entre 1 µm et 5 mm. Ils résultent soi ...

Fully rehabilitation: integrating a small hydro cascade into a water supply system

Pedro Filipe De Almeida Manso

A rehabilitation scheme at the more than 100 year-old Fully hydro scheme, where the penstock had shown signs of ageing, has involved converting the original single power station into a cascade of three plants, which have been integrated in a municipal wate ...

Opportunity and Economic Feasibility of Inline Microhydropower Units in Water Supply Networks

Anton Schleiss, Pedro Filipe De Almeida Manso, Mário Jorge Rodrigues Pereira Da Franca, Irene Almeida Samora

Small-scale hydropower is emerging as a decentralized source to satisfy local demand for electricity. In water supply systems, microhydropower can be used for energy recovery associated with excessive pressure control. However, there is a lack of specific ...

Simulated Annealing in Optimization of Energy Production in a Water Supply Network

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Irene Almeida Samora

In water supply systems, the potential exists for micro-hydropower that uses the pressure excess in the networks to produce electricity. However, because urban drinking water networks are complex systems in which flows and pressure vary constantly, identif ...

Feasibility assessment of micro-hydropower for energy recovery in the water supply network of the city of Fribourg

Anton Schleiss, Pedro Filipe De Almeida Manso, Mário Jorge Rodrigues Pereira Da Franca, Irene Almeida Samora

In water supply systems there is potential for hydropower production at several scales, from small hydro to micro. The energy recovery within the urban water supply networks is a type of micro-hydro that may be useful for the control of excessive pressures ...

Optimization of low-head hydropower recovery in water supply networks

Irene Almeida Samora

Water supply networks in cities with sloping topography may have a considerable potential for the installation of micro hydropower plants. Since these water supply networks are complex systems with many constraints, the identification of the best locations ...

Point-of-use water filters can effectively remove disinfection by-products and toxicity from chlorinated and chloraminated tap water

Urs von Gunten

Epidemiological risk estimates point toward potential health risks posed by disinfection by-products ( DBPs) in chlorinated drinking water. Point-of-use filters can effectively remove regulated DBPs from tap water but the removal of unknown DBPs and toxici ...

A new robust oxygen-temperature sensor for aquatic eddy covariance measurements

Alfred Johny Wüest, Hua Li

The fragility of thin Clark-type glass microelectrodes used in aquatic eddy covariance measurements of benthic oxygen fluxes is a challenge when using this powerful technique. This study presents a new fast-responding dual oxygen-temperature sensor for edd ...

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, ...
