Temporal variability of antibiotics fluxes in wastewater and contribution from hospitals

David Andrew Barry, Luca Rossi, Sylvain Coutu

Significant quantities of antibiotics are used in all parts of the globe to treat diseases with bacterial origins. After ingestion, antibiotics are excreted by the patient and transmitted in due course to the aquatic environment. This study examined tempor ...

Laccases: Potential treatment for removal of micropollutants in municipal wastewater?

David Andrew Barry, Christof Holliger, Julien Maillard, Jonas Margot

Relatively high concentrations of micropollutants such as pharmaceuticals and biocides in municipal wastewater treatment plants (WWTP) effluents underscore the necessity to develop new treatments. Organisms that produce oxidative enzymes such as laccases a ...

La contamination du Léman par les micropolluants – revue de 40 ans d’études

Luiz Felippe De Alencastro

Lake Geneva pollution by micropollutants – a review of 40 years of study. – Lake Geneva drains a watershed of about 8000 km2, subject to anthropogenic pressures due to a large population, agriculture, and industries. Contaminants released by these activiti ...

Quantitative structure–activity relationships (QSARs) for the transformation of organic micropollutants during oxidative water treatment

Urs von Gunten, Yun Ho Lee

Various oxidants such as chlorine, chlorine dioxide, ferrateVI, ozone, and hydroxyl radicals can be applied for eliminating organic micropollutant by oxidative transformation during water treatment in systems such as drinking water, wastewater, and water r ...

Investigation of the Electrochemical Destruction of X-ray Contrast Media using Boron-‐Doped Diamond Electrodes (BDD)

Guillaume Tissot

Iodinated X-ray contrast media (ICM) are persistent micropollutants in wastewater, which come mainly from hospital activities. Currently, there is no efficient method of treatment for this class of compounds, which leads to their increased presence in surf ...

Determination of optimal conditions for the degradation of micropollutants by laccase from Trametes versicolor

David Andrew Barry, Christof Holliger, Julien Maillard, Luca Rossi, Jonas Margot

Many hydrophilic organic compounds present at low concentrations in municipal wastewater, such as several pharmaceuticals, biocides and pesticides, are recalcitrant in conventional wastewater treatment plants. To improve the biodegradation of these compoun ...

Chemistry of Ozone in Water and Wastewater Treatment

Urs von Gunten

Even though ozone has been applied for a long time for disinfection and oxidation in water treatment, there is lack of critical information related to transformation of organic compounds. This has become more important in recent years, because there is con ...

Degradation of 37 emergent contaminants by UV and neutral fenton and photo-fenton in domestic wastewater effluent previously treated by activated sludge

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Natalia de la Cruz

This study focuses on the removal of 32 selected micropollutants (pharmaceuticals, corrosion inhibitors and biocides/pesticides) found in an effluent coming from a municipal wastewater treatment plant (MWTP) based on activated sludge. Dissolved organic mat ...

Evaluation des incertitudes dans la mesure des micropolluants

Sylvain Gorgerat

Occurrence and fate of micropollutants in surface water are of growing concern. To take adequate actions, it is essential to rely on representative data. Therefore, it is necessary to assess uncertainties related to the different steps of the analytical pr ...

Effects of sonochemical parameters and inorganic ions during the sonochemical degradation of crystal violet in water

César Pulgarin, Fernando Guzman Duque

This work deals with the ultrasonic degradation (800 kHz) of crystal violet (CV) under different experimental conditions. The effects of saturating gas (argon, carbon dioxide and air), CV concentration (2.45-1225 mu mol L-1), pH (3-9) and power (20-80 W) w ...
