Vision-based system for the control and measurement of wastewater flow rate in sewer systems

David Andrew Barry, Luca Rossi, Daniel Sage, Laurent Son Nguyen, Salim Kayal

Combined sewer overflows and stormwater discharges represent an important source of contamination to the environment. However, the harsh environment inside sewers and particular hydraulic conditions during rain events reduce the reliability of traditional ...

Equilibrium desorption isotherms of water, ethanol, ethyl acetate and toluene on a sodium smectite clay

John Christopher Plummer, Pascal Clausen

Desorption isotherms for water, ethanol, ethyl acetate and toluene from a sodium smectite clay have been determined by both dynamic vapor sorption (DVS) measurements and Knudsen thermogravimetry (KTGA), at the exception of toluene that was measured only by ...

Elimination of Organic Micropollutants in a Municipal Wastewater Treatment Plant Upgraded with a Full-Scale Post-Ozonation Followed by Sand Filtration

Urs von Gunten, Juliane Hollender, Hansruedi Siegrist

The removal efficiency for 220 micropollutants was studied at the scale of a municipal wastewater treatment plant (WWTP) upgraded with post-ozonation followed by sand filtration. During post-ozonation, compounds with activated aromatic moieties, amino func ...

Trihalomethane formation during water disinfection in four water supplies in the Somes river basin in Romania

Urs von Gunten

Background, aim and scope After the discovery of chloroform in drinking water, an extensive amount of work has been dedicated to the factors influencing the formation of halogenated disinfections by-products (DBPs). The disinfection practice can vary signi ...

Individual cells immobilization for water-borne pathogen detection and enumeration

A cell counting device has been proposed and implemented for water-borne pathogen detection for drinking water quality monitoring applications. Our approach is based on magnetically-labelled cells immobilization in a high density array of individual cell f ...

3D-microstructure analysis of hydrated bentonite with cryo- stabilized pore water

Marta Rizzi

In saturated bentonite, free water is hosted in the meso- and macropores. Microscopic characterization of free water and the associated pore structure is very difficult because of the swelling- and shrinking-behaviour of montmorillonite. In this article, w ...

Design approach for the improvement of the economic and environmental performances of potable water supply

François Vince

Triggered by the Kyoto Protocol and by the aggravation of freshwater scarcity, environmental impacts should soon become key decision criteria for the planning of potable water supply projects, especially when advanced systems such as seawater desalination ...

Ozonation of Source-Separated Urine for Resource Recovery and Waste Minimization: Process Modeling, Reaction Chemistry, and Operational Considerations

Urs von Gunten

Bench-scale, semibatch experiments were performed to examine physical-chemical constraints on ozone (O-3) absorption and micropollutant oxidation during ozonation of source-separated hydrolyzed urine and the concentrate and diluate streams produced via ele ...

Phototransformation of selected pharmaceuticals during UV treatment of drinking water

Urs von Gunten, Silvio Canonica

The kinetics of Ultraviolet C (UV-C)-induced direct phototransformation of four representative pharmaceuticals, i.e., 17 alpha-ethinylestradiol (EE2), diclofenac, sulfa methoxazole, and iopromide, was investigated in dilute solutions of pure water buffered ...

A Document Reuse Tool for Communities of Practice

Stéphane Sire, Micaël Paquier, Christine Vanoirbeek, Aïda Boukottaya, Loïc Merz

Virtual communities of practice are gaining importance as mean of sharing and exchanging knowledge. In such environments, information reuse is of major concern. In this paper, we outline the importance of structuring documents in order to facilitate the re ...
