Application of the analytic hierarchy process to the analysis of wastewater nutrient recycling options: a case based on a group study of residents in the city of Zurich

The recycling of anthropogenic nutrients derived from the wastewater management systems is often characterized by a complex and uncertain scenario, due not only to the nature of the process but also to the involvement of different stakeholder groups. Over ...

Optimized aeration strategies for nitrogen and phosphorus removal with aerobic granular sludge

Christof Holliger, Samuel Lochmatter, Graciela Gonzalez Gil

Biological wastewater treatment by aerobic granular sludge biofilms offers the possibility to combine carbon (COD), nitrogen (N) and phosphorus (P) removal in a single reactor. Since denitrification can be affected by suboptimal dissolved oxygen concentrat ...

Bacterial selection for nutrient removal in aerobic granular sludge wastewater treatment systems

Christof Holliger, David Gregory Weissbrodt

The mechanism of bacterial selection was investigated in aerobic granular sludge wastewater treatment systems (i) to determine why biological nutrient removal (BNR) gets deteriorated during granulation start-up under wash-out dynamics, and (ii) to identify ...

Detection and quantification of ionophore antibiotics in runoff, soil and poultry litter

Delphine Barmaz

Ionophore antibiotics (IPAs) are widely used as coccidiostats in poultry and other livestock industries to promote growth and prevent infections. Because most of the ingested IPAs are excreted in poultry litter, which is primarily applied as grassland fert ...

Analysis of carbon and nitrogen dynamics in riparian soils: Model development

David Andrew Barry, Alessandro Brovelli, Jordi Batlle-Aguilar

The quality of riparian soils and their ability to buffer contaminant releases to aquifers and streams are connected intimately to moisture content and nutrient dynamics, in particular of carbon (C) and nitrogen (N). A multi-compartment model – named the R ...

Dominant controls on pesticide transport from tile to catchment scale: Lessons from a minimalist model

Andrea Rinaldo, Gianluca Botter

This paper proposes a minimalist modeling approach for characterizing pesticide concentrations in runoff from agricultural catchments across spatial scales. The model proposed is of an intermediate level of complexity between traditional chromatographic se ...

A sustainable production of algal biomass integrating wastewater treatment and bioenergy generation

Christian Ludwig, Céline Terrettaz, Mariluz Bagnoud

This project aims to demonstrate the feasibility of producing renewable microalgae biomass using as a main nutrient source a secondary wastewater stream. It is planned to purify the wastewater by the growth of algal biomass while producing a feedstock that ...

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- ...

Dilute nitride InGaAsN/GaAs V-groove quantum wires emitting at 1.3 μm wavelength at room temperature

Elyahou Kapon, Alok Rudra, Marco Cantoni, Barbora Bártová, Romain Carron, Pascal Gallo, Marco Felici

Site-controlled InGaAsN quantum wires (QWRs) emitting at 1.3 lm at room temperature were grown on V-grooved GaAs substrates by modulated-flux metallorganic vapor phase epitaxy. The nonplanar substrate template is shown to enhance the nitrogen uptake, evide ...
