Hydraulic performance of stepped spillway aerators and related downstream flow features

To protect spillways against cavitation damage, adding a small air concentration to the flow close to the invert is efficient. Aerator performance on smooth chutes was therefore well studied in terms of air entrainment and downstream air concentration deve ...

Evaluation des flux de biphényles polychlorés (PCBs) dans les affluents du lac Léman à l’aide de capteurs passifs

The aim of this study is to investigate Lake Geneva’s tributaries using passive samplers in order to establish polychlorinated biphenyl (PCB) fluxes. Silicon rubber sheets are therefore deployed during six weeks at the mouth of eight tributaries and in fou ...

Evolution of microbial communities and nutrient removal performances in aerobic granular sludge sequencing batch reactor during change of substrate

Christof Holliger, Julien Maillard, Aline Sondra Adler, Valérie Berclaz, Marie Christelle Horisberger

• Aerobic granular sludge (AGS) is a promising alternative wastewater treatment to the conventional activated sludge system. As AGS has enhanced settling abilities and provides different redox conditions across the granules at the same time, the processes ...

Potential of horseradish hairy roots for the phytotreatment of water containing sulfamethoxazole

Salome Julia Laake

The continuous accumulation of micropollutants in water is a growing problem for our water resources. Currently, most conventional wastewater treatment plants (WWTP) are not able to remove them efficiently. Several pharmaceuticals, for which the measured c ...

Understanding what limits biological phosphorus removal at Uster’s wastewater treatment plant

This study aims at better understanding what limits the biological phosphate removal at Uster’s wastewater treatment plant (WWTP). Two hypotheses were proposed to explain the limited biological phosphate removal observed at Uster’s WWTP: (i) A heterogeneou ...

Degradation of Eight Relevant Micropollutants in Different Water Matrices by Neutral Photo-Fenton Process under UV254 and Simulated Solar Light Irradiation – a comparative study

César Pulgarin, Andrzej Sienkiewicz, Dominique Grandjean, Luiz Felippe De Alencastro

This is a comparative study of photolytic degradation under exposure to UV254 nm and solar-simulator irradiation of a mixture of eight equally concentrated relevant micropollutants in the presence of H2O2 and Fe(II) in ultrapure water, Lake Geneva water, a ...

Multilevel Correlations in the Biological Phosphorus Removal Process: from Bacterial Enrichment to Conductivity-Based Metabolic Batch Tests and Polyphosphatase Assays

Christof Holliger, Julien Maillard, Alessandro Brovelli, David Gregory Weissbrodt, Alexandre Chabrelie, Jonathan May

Enhanced biological phosphorus removal (EBPR) from wastewater relies on the preferential selection of active polyphosphate-accumulating organisms (PAO) in the underlying bacterial community continuum. Efficient management of the bacterial resource requires ...

Inﬂuence of a wastewater treatment plant on mercury contamination and sediment characteristics in Vidy Bay (Lake Geneva, Switzerland)

Yosef Akhtman, Serge Stoll, Neil Graham

Previous direct observations of the sediment surface in Vidy Bay, Lake Geneva (Switzerland), revealed a range of sediment characteristics in terms of colour, texture and morphology. Dives with the MIR submersibles during the éLEMO project permitted the exp ...
