Non-target screening to trace ozonation transformation products in a wastewater treatment train including different post-treatments

Ozonation and subsequent post-treatments are increasingly implemented in wastewater treatment plants (WWTPs) for enhanced micropollutant abatement. While this technology is effective, micro pollutant oxidation leads to the formation of ozonation transforma ...

Ecological strategies and metabolic trade-offs of complex environmental biofilms

Tom Ian Battin, Hannes Markus Peter

Microorganisms aggregated into matrix-enclosed biofilms dominate microbial life in most natural, engineered, and medical systems. Despite this, the ecological adaptations and metabolic trade-offs of the formation of complex biofilms are currently poorly un ...

Reactive surface organometallic complexes observed using dynamic nuclear polarization surface enhanced NMR spectroscopy

David Lyndon Emsley, Jasmine Viger-Gravel, David Benjamin Roger Antoine Gajan

Dynamic Nuclear Polarization Surface Enhanced NMR Spectroscopy (DNP SENS) is an emerging technique that allows access to high-sensitivity NMR spectra from surfaces. However, DNP SENS usually requires the use of radicals as an exogenous source of polarizati ...

Enhancing the photo-Fenton treatment of contaminated water by use of ultrasound and iron-complexing agents

Stefanos Papoutsakis

The photo-Fenton process is a promising emerging technology for the treatment of contaminated water streams. It is based on the generation of reactive oxygen species that are capable of destroying recalcitrant contaminants otherwise unaffected by conventio ...

Reversible supramolecular modification of surfaces

Negar Moridi

Enzymes are biocatalysts widely used in a large number of industrial biotech processes as they offer clear advantages over their chemical counterparts. Indeed, enzymes often show high substrate selectivity along with elevated turnover rates. Enzymatic cata ...

The biofilm granulation mechanisms depend on the predominant bacterial populations involved

Christof Holliger, David Gregory Weissbrodt

Introduction Aerobic granular sludge used for intensified biological wastewater treatment is based on fast-settling mobile biofilms with a gel-like consistence, called “granules”, formed from activated sludge flocs (Seviour et al. 2012). Fundamental aspect ...

Light and hydrologic variability as drivers of stream biofilm dynamics in a flume experiment

Andrea Rinaldo, Tom Ian Battin, Enrico Bertuzzo, Lorenzo Mari, Serena Ceola, Marino Gatto, Gianluca Botter

We run a comparative study of the results of flume experiments and several dynamic models reproducing the effects of streamflow variability on biofilm (i.e. periphyton) temporal dynamics. During the experiment, two contrasting flow regimes, characterised b ...

Hybrid polarizing solids for pure hyperpolarized liquids through dissolution dynamic nuclear polarization

David Lyndon Emsley, Geoffrey Bodenhausen, Aurélien Bornet, Sami Jannin, Jonas Milani, Basile Vuichoud, David Benjamin Roger Antoine Gajan

Hyperpolarization of substrates for magnetic resonance spectroscopy (MRS) and imaging (MRI) by dissolution dynamic nuclear polarization (D-DNP) usually involves saturating the ESR transitions of polarizing agents (PAs; e.g., persistent radicals embedded in ...

Treatment of micropollutants in municipal wastewater using white-rot fungi

David Andrew Barry, Christof Holliger, Jonas Margot, Andreu Contijoch Culleré

Treatment of micropollutants such as pharmaceuticals and pesticides in municipal wastewater is challenging due to their very low concentrations (ng/l to µg/l), their relatively low biodegradability, and their different physico-chemical characteristics. One ...

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 ...
