Role of ammonia-oxidizing bacteria in micropollutant removal from wastewater with aerobic granular sludge

Christof Holliger, Samuel Lochmatter, Jonas Margot, David Andrew Barry

Nitrifying wastewater treatment plants (WWTPs) are more efficient than non-nitrifying WWTPs to remove several micropollutants such as pharmaceuticals and pesticides. This may be related to the activity of nitrifying organisms, such as ammonia-oxidizing bac ...

Sulfamethoxazole and isoproturon degradation and detoxification by a laccase-mediator system: Influence of treatment conditions and mechanistic aspects

Christof Holliger, Pierre-Jean Copin, Jonas Margot, David Andrew Barry, Urs von Gunten

The potential of laccase-mediator systems (LMS) for the removal and detoxification of two wastewater micropollutants, the antibiotic sulfamethoxazole (SMX) and the herbicide isoproturon (IPN), was assessed. The influence of various parameters on micropollu ...

A review of the fate of micropollutants in wastewater treatment plants

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

Municipal wastewaters are contaminated by a wide range of chemicals, from surfactants to heavy metals, including pharmaceutical residues, personal care products, various household chemicals, and biocides/pesticides. Their release into the environment, wher ...

Micropollutant removal from municipal wastewater : from conventional treatments to advanced biological processes

Jonas Margot

Many micropollutants present in municipal wastewater, such as pharmaceuticals and pesticides, are poorly removed in conventional wastewater treatment plants (WWTPs), and may generate adverse effects on aquatic life. The objective of this thesis was to stud ...

Influence of treatment conditions on the oxidation of micropollutants by Trametes versicolor laccase

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

Many organic compounds present at low concentrations in municipal wastewater, such as various pharmaceuticals and biocides, are recalcitrant in conventional wastewater treatment plants (WWTPs). To improve their biodegradation, oxidoreductase enzymes such a ...

Sediment contamination assessment in urban areas based on total suspended solids

Nathalie Chèvre Rossi, Luca Rossi, Romuald Curdy, Jonas Margot, David Andrew Barry

Sediment represents an important compartment in surface waters. It constitutes a habitat or spawning site for many organisms and is an essential trophic resource for higher level organisms. It can be impacted by anthropogenic activities, particularly throu ...

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

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

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 ...

Enhancement of micropollutant degradation at the outlet of small wastewater treatment plants

Luca Rossi, Jonas Margot, Pierre Claude Jean Queloz, David Andrew Barry, Alessandro Brovelli

The aim of this work was to evaluate low-cost and easy-to-operate engineering solutions that can be added as a polishing step to small wastewater treatment plants to reduce the micropollutant load to water bodies. The proposed design combines a sand filter ...

Treatment of micropollutants in municipal wastewater: Ozone or powdered activated carbon?

Luca Rossi, Luiz Felippe De Alencastro, Jonas Margot, Anoys Magnet, David Andrew Barry

Many organic micropollutants present in wastewater, such as pharmaceuticals and pesticides, are poorly removed in conventional wastewater treatment plants (WWTPs). To reduce the release of these substances into the aquatic environment, advanced wastewater ...

Bacterial versus fungal laccase: potential for micropollutant degradation

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

Relatively high concentrations of micropollutants in municipal wastewater treatment plant (WWTP) effluents underscore the necessity to develop additional treatment steps prior to discharge of treated wastewater. Microorganisms that produce unspecific oxida ...
