Management of turbidity current venting in reservoirs under different bed slopes

Anton Schleiss, Giovanni De Cesare, Sabine Chamoun

The lifetime and efficiency of dams is endangered by the process of sedimentation. To ensure the sustainable use of reservoirs, many sediment management techniques exist, among which venting of turbidity currents. Nevertheless, a number of practical questi ...

Carbon cycling and carbon dioxide dynamics during ice-cover in great Lake Onego, Russia

The Great European Lake Onego provides important resources for Northern Russia. This lake is ice-covered during 5 months in winter. However, very few data are available for winter, as most studies covered the ice-free period. Actually, comprehension of sea ...

Calibration and deployment of POCIS and Chemcatcher for the monitoring of explosives on lake-bottom sediments

Luiz Felippe De Alencastro, Nicolas Estoppey

Between 1920 and 1967, approximatively 8000 tons of ammunition waste was dumped into some Swiss lakes. Previous studies based on grab sampling revealed small traces of cyclotetramethylenetetranitramine (HMX), cyclotrimethylenetrinitramine (RDX) and pentaer ...

Bacterial inactivation with iron citrate complex: A new source of dissolved iron in solar photo-Fenton process at near-neutral and alkaline pH

César Pulgarin, Andrzej Sienkiewicz, Cristina del Socorro Lonfat

This study reports the first application of Fe-citrate-based photo-Fenton chemistry for the inactivation of Escherichia coil. Promising results of bacterial inactivation at near-neutral and alkaline pH conditions were obtained, while using low iron concent ...

Iron-oxides and iron-citrate as new photocatalysts in solar inactivation of Escherichia coli in water

Cristina del Socorro Lonfat

This study addresses the bacterial inactivation mechanism by photo-Fenton process at near-neutral pH, focusing on iron-oxides and iron-citrate as photocatalysts for solar water disinfection and using E. coli as a bacteria model. Cell envelope damage during ...

Fe vs. TiO2 Photo-assisted Processes for Enhancing the Solar Inactivation of Bacteria in Water

César Pulgarin

Batch solar water disinfection (SODIS) is a known, simple and low-cost water treatment technology. SODIS is based on the synergistic action of temperature increase and light-assisted generation of Reactive Oxygen Species (ROS) on bacteria. ROS are generate ...

Applications of Pinch Analysis and Mathematical Programming Methods for Synthesizing Non-Isothermal Water Networks

François Maréchal, Maziar Kermani

Processes industries consume large amounts of natural resources and generate large amounts of waste/emissions into the environment. Consequently, important issues and challenges within the process industries are rational use of raw materials, water and ene ...

Pyrolysis for coffee pulp valorization

Much literature about the use of pyrolysis in the coffee production sector focuses on a stationary plant design. We evaluate the benefits of a mobile plant to also serve small coffee farmers where the harvesting season lasts only about three months. In suc ...

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 ...
