Prediction of Micropollutant Elimination during Ozonation of Municipal Wastewater Effluents: Use of Kinetic and Water Specific Information

Ozonation, is effective in improving the quality of, municipal wastewater effluents by eliminating organic micropollutants. Nevertheless, ozone process design is still limited by (i) the large number of structurally diverse micropollutants and (ii) the var ...

Implementation of a genetic transformation strategy to improve the biological CO2 capture in Chlorella sp. and Scenedesmus sp.

Christian Ludwig, Mariluz Bagnoud

The concept of producing renewable microalgae biomass using as a main nutrient source a secondary wastewater stream is presently under investigation. It is planned to purify the wastewater by the growth of algal biomass while producing a feedstock that can ...

A European perspective on alternatives to animal testing for environmental hazard identification and risk assessment

Kristin Schirmer

Tests with vertebrates are an integral part of environmental hazard identification and risk assessment of chemicals, plant protection products, pharmaceuticals, biocides, feed additives and effluents. These tests raise ethical and economic concerns and are ...

An application of a decision tree for assessing effects from exposures to multiple substances to the assessment of human and ecological effects from combined exposures to chemicals observed in surface waters and waste water effluents

Xiaoxue Han

A decision tree has been developed for evaluating risks posed by combined exposures to multiple chemicals. The decision tree divides combined exposures of humans and ecological receptors into groups where one or more components are a concern by themselves, ...

LOCALIZATION OF POINT SOURCES OF POLYCHLORINATED BIPHENYLS (PCBs) POLLUTION IN RIVERS USING PASSIVE SAMPLERS

Luiz Felippe De Alencastro, Jonas Milani, Nicolas Estoppey, Julien Omlin, Jan Philipp Robra, Louise Gilbert, Juliana León, Nancy El Ghorayeb

Polychlorinated biphenyls (PCBs) are universal environmental contaminants that have attracted great concern because of their worldwide distribution, persistence in the environment and possible harmful effects. Recycling old objects or materials containing ...

Towards the sustainable cultivation of microalgae for the production of biofuels and added-value chemicals

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

Microalgae represent an attractive source of biomass for biofuels and chemicals production since they can have higher energy yields per area than conventional biomass crops and can be grown on marginal land using waste, saline, or brackish water. Their use ...

Removal of the antiviral agent oseltamivir and its biological activity by oxidative processes

Urs von Gunten, Kristin Schirmer, Silvio Canonica

The antiviral agent oseltamivir acid (OA, the active metabolite of Tamiflu) may occur at high concentrations in wastewater during pandemic influenza events. To eliminate OA and its antiviral activity from wastewater, ozonation and advanced oxidation proces ...
