LC-MS/MS determination of potential endocrine disruptors of cortico signalling in rivers and wastewaters

A targeted analytical method was established to determine a large number of chemicals known to interfere with the gluco- and mineralocorticoid signalling pathway. The analytes comprise 30 glucocorticoids and 9 mineralocorticoids. Ten out of these corticost ...

Conception of a biological activated carbon filter for micropollutants removal in wastewater

Solène Gomez

The presence of micro pollutants in water is an important emerging problem because of their negative impacts on health and environment. The Swiss Federal Office of the Environment is planning to impose new regulations to reduce the load of micro pollutants ...

Bacterial resource management for nutrient removal in aerobic granular sludge

David Gregory Weissbrodt

A holistic approach was developed towards efficient bacterial resource management for nutrient removal from wastewater in aerobic granular sludge sequencing batch reactors. Multiple reactor experiments from granulation start-up to operation at steady-state ...

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 ...

Analysis of N-nitrosamines and other nitro(so) compounds in water by high-performance liquid chromatography with post-column UV photolysis/Griess reaction

Urs von Gunten, Minju Lee, Yun Ho Lee

Despite their potential carcinogenicity and probable formation during water disinfection processes, little is known about the occurrence of other nitro(so) compounds than a few specific N-nitroso compounds such as N-nitrosodimethylamine (NDMA). An analytic ...

Bacterial Resource Management for Nutrient Removal in Aerobic Granular Sludge Wastewater Treatment Systems

David Gregory Weissbrodt

The approach of wastewater treatment has shifted towards a holistic view in order to achieve sustainability in addition to environmental protection. The aerobic granular sludge (AGS) technology, which relies on the use of fast-settling granular biofilms ca ...

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 ...

Optimization of Reactor Startup and Nitrogen Removal of Aerobic Granular Sludge Systems

Samuel Lochmatter

Aerobic granular sludge (AGS) in sequencing batch reactors (SBR) has recently made its proofs as full-scale technology for the biological treatment of urban wastewater. In contrast to conventional flocculent activated sludge, microorganisms aggregate to de ...

Bacterial versus fungal laccase: potential for micropollutant degradation

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

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 ...
