Iron-coated polymer films with high antibacterial activity under indoor and outdoor light, prepared by different facile pre-treatment and deposition methods

César Pulgarin, Sami Rtimi, Stefanos Giannakis, Laura Victoria Suárez Murillo, Ania Schärer

In the present work, we study the fabrication of self-cleaning antibacterial surfaces, active under indoor or outdoor light. In order to obtain the highest activity with the lowest complexity we assess mild conditions of preparation (temperatures), pre-tre ...

Surface water treatment by UV/H2O2 with subsequent soil aquifer treatment: impact on micropollutants, dissolved organic matter and biological activity

Urs von Gunten, Fabienne Eugster, Thomas Wintgens

Because organic micropollutants (MP) are frequently detected in river waters that are used as drinking water sources, combining a relatively cost-efficient natural treatment with upstream advanced oxidation processes (AOP) appears promising for their effic ...

Enhancement of micropollutant degradation at the outlet of small wastewater treatment plants

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Jonas Margot, Pierre Claude Jean Queloz

The aim of this work was to evaluate low-cost and easy-to-operate engineering solutions that can be added as a polishing step to small wastewater treatment plants to reduce the micropollutant load to water bodies. The proposed design combines a sand filter ...

Impacts of irrigation with industrial treated wastewater on soil properties

André Mermoud, Pascal Boivin

Wastewater reuse in agriculture is a widespread practice in developing countries, especially in urban areas where water shortage and poverty encourage people to use that marginal resource. Raw or treated wastewaters are used by farmers, but even treated wa ...

Bioethanol production from oil palm empty fruit bunches : a comparison among different pretreatment options

Simone Chiesa

Face to the increasing demand for energy, the declining availability of fossil fuels and the periodical tensions in the geopolitical context of oil-producing countries have raised serious concerns in the governments worldwide as well as in the public opini ...

Design methodology accounting for the effects of porous medium heterogeneity on hydraulic residence time and biodegradation in horizontal subsurface flow constructed wetlands

David Andrew Barry, Luca Rossi, Alessandro Brovelli, Otoniel Carranza Diaz

Horizontal flow constructed wetlands are engineered systems capable of eliminating a wide range of pollutants from the aquatic environment. Nevertheless, poor hydrodynamic behavior is commonly found resulting in preferential pathways and variations in both ...

Bioclogging in porous media: Model development and sensitivity to initial conditions

David Andrew Barry, Alessandro Brovelli, Flavio Malaguerra

This work presents a numerical model able to simulate the effect of biomass growth on the hydraulic properties of saturated porous media, i.e., bioclogging. A new module for an existing coupled flow and reactive-transport code -- PHWAT -- was implemented. ...
