Development of a microalgal process for bioenergy production, CO2 mitigation and wastewater treatment

Christof Holliger, Jean-Paul Schwitzguebel, Gabrielle Hack, Charlotte Pfistner

Over the last decade, intensive research has been carried out all over the world to explore the huge potential of microalgae for biofuel production, which could be coupled to the use of industrial flue gas to enhance CO2 fixation as a greenhouse gas mitiga ...

Trade-Offs in Disinfection Byproduct Formation Associated with Precursor Preoxidation for Control of N-Nitrosodimethylamine Formation

Urs von Gunten

Chloramines in drinking water may form N-nitrosodimethylamine (NDMA). Various primary disinfectants can deactivate NDMA precursors prior to chloramination. However, they promote the formation of other byproducts. This study compared the reduction in NDMA f ...

Degradation of 37 emergent contaminants by UV and neutral fenton and photo-fenton in domestic wastewater effluent previously treated by activated sludge

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Natalia de la Cruz

This study focuses on the removal of 32 selected micropollutants (pharmaceuticals, corrosion inhibitors and biocides/pesticides) found in an effluent coming from a municipal wastewater treatment plant (MWTP) based on activated sludge. Dissolved organic mat ...

Optimization of water quality monitoring network in large river by combining measurements, a numerical model and matter-element analysis

Koen Blanckaert

A monitoring network that resolves the spatial and temporal variations of the water quality is essential in the sustainable management of water resources and pollution control. Due to cost concerns, it is important to optimize the monitoring locations so t ...

Significant decrease of THMs generated during chlorination of river water by previous photo-Fenton treatment at near neutral pH

César Pulgarin

An important issue in chlorine drinking water disinfection is the generation from natural organic matter (NOM) of disinfection by-products (DBPs), especially trihalomethanes (THMs). The THMs generation can be limited by reducing the levels of NOM prior to ...

Investigation of the Electrochemical Destruction of X-ray Contrast Media using Boron-‐Doped Diamond Electrodes (BDD)

Guillaume Tissot

Iodinated X-ray contrast media (ICM) are persistent micropollutants in wastewater, which come mainly from hospital activities. Currently, there is no efficient method of treatment for this class of compounds, which leads to their increased presence in surf ...

Energy and water conservation from air handling unit condensate in hot and humid climates

Dusan Licina

This study investigates the potential for energy and water sustainability in hot and humid climates by utilizing the condensate captured from large dedicated air handling units (AHUs) for pre-cooling outdoor air in another AHU and subsequently offsetting c ...

Towards the sustainable cultivation of microalgae to produce renewable biofuels and added-value chemicals

Christof Holliger, Christian Ludwig, Jean-Paul Schwitzguebel, Mariluz Bagnoud, Eduardo Pereira Gomes

Microalgal cultures represent a promising alternative source of biomass for biofuel and chemicals production, since they can reach higher energy yields per area than conventional biomass crops and can be grown on marginal land using waste, saline or bracki ...

Reusable Nanostencils for Creating Multiple Biofunctional Molecular Nanopatterns on Polymer Substrate

Hatice Altug, Serap Aksu, Min Huang

In this paper, we demonstrate a novel method for high throughput patterning of bioprobes with nanoscale features on biocompatible polymer substrate. Our technique, based on nanostencil lithography, employs high resolution and robust masks integrated with a ...

Reuse of domestic wastewater treated in macrophyte ponds to irrigate tomato and eggplant in semi-arid West-Africa: benefits and risks

André Mermoud

The scarcity of freshwater resources is a critical problem in semi-arid zones and marginal quality water is increasingly being used in agriculture. This paper aimed at evaluating the physico-chemical and biological risks on irrigated soils and fruits of ma ...
