Photocatalytic performance of TiO2 impregnated polyester for the degradation of Reactive Green 12: Implications of the surface pretreatment and the microstructure

Sami Rtimi

In the present work, we investigate the degradation of recalcitrant industrial textile dye (Reactive green 12) in aqueous solution by TiO2 impregnated polyester at room temperature. The TiO2 loading on polyester was optimized using different polyester pret ...

Fine sediment routing in a cascade of alpine reservoirs: Influence of the inlet angle on settling of fine sediments

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

Reservoir sedimentation is, at present, one of the main concerns in the operational management of dams. The resulting reduction of storage capacity has negative impacts on the hydropower production, flood protection, and availability of water for irrigatio ...

Continuous Long-Term Observation of Suspended Sediment Transport between Two Pumped-Storage Reservoirs

Anton Schleiss, Giovanni De Cesare, Michael Müller

Transport of suspended sediment between the two reservoirs of a pumped-storage plant in Switzerland was monitored over an 8-month period. A turbidity probe was installed on the upstream end of the pressure shaft, in which real-time monitoring was ensured b ...

Sediment contamination assessment in urban areas based on total suspended solids

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

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 ...

Nanostructured Catalysts for the Continuous Reduction of Nitrates and Bromates in Water

Lioubov Kiwi

Nanostructured C-based catalysts have been developed to be used in continuously operated (open-flow) reactors for the removal of bromates and nitrates from polluted water. The catalysts contain transition-metal (Pd, Cu, and Sn) nanoparticles (NPs) supporte ...

Sources, Spreading and Fate of Antibiotic Resistance Genes and Resistant Bacteria in Vidy Bay, Lake Geneva, Switzerland

Nadine Czekalski

Increasing numbers of multiresistant bacterial pathogens cause severe health problems on a global scale. Large quantities of bacteria and their resistance genes are discharged into natural environments via human and animal waste. Not much is known so far a ...

Energy recovery in SUDS towards smart water grids: A case study

Anton Schleiss, Irene Almeida Samora

The development of a methodology for urban flood adaptation and energy recovery solutions is resting on the concept of Sustainable Urban Drainage Systems (SUDS) as a measure to reduce risks of urban flooding while fully utilizing the available resources. F ...

Parsimonious hydrological modelling in urban areas: Towards integrated modelling

David Andrew Barry, Luca Rossi, Sylvain Coutu, Dario Del Giudice

Most popular urban hydrological model used in research and engineering (e.g. MOUSE, SWMM, MUSIC,P8) are spatially distributed with linknode drainage network. If some of them (e.g. PURPS, RUNQUAL, SLAMM, StormTac and WBM) treat the catchment in a lumped fas ...

Parsimonious hydrological modeling of urban sewer and river catchments

David Andrew Barry, Luca Rossi, Sylvain Coutu, Dario Del Giudice

A parsimonious model of flow capable of simulating flow in natural/engineered catchments and at WWTP (Wastewater Treatment Plant) inlets was developed. The model considers three interacting, dynamic storages that account for transfer of water within the sy ...

Snowfall Limit Forecasts and Hydrological Modeling

Andrea Rinaldo, Cara Christine Tobin, Bettina Schaefli

Hydrological flood forecasting in mountainous areas requires accurate partitioning between rain and snowfall to properly estimate the extent of runoff contributing areas. Here a method to make use of snowfall limit information-a standard output of limited- ...
