Unfolding the action mode of light and homogeneous vs. heterogeneous photo-Fenton in bacteria disinfection and concurrent elimination of micropollutants in urban wastewater, mediated by iron oxides in Raceway Pond Reactors

César Pulgarin, Florian Frédéric Vincent Breider, Dominique Grandjean, Stefanos Giannakis, Irene De La Obra Jimenez

In this work, iron oxides have been proposed as low-cost heterogeneous photo-Fenton catalysts for the simultaneous disinfection and reduction of microcontaminant load from urban wastewater in raceway pond reactors at near-neutral pH. The objective was not ...

Occurrence of organic micropollutants and human health risk assessment based on consumption of Amaranthus viridis, Kinshasa in the Democratic Republic of the Congo

Florian Frédéric Vincent Breider, Dominique Grandjean

The contamination of water resource and food chain by persistent organic pollutants (POPs) constitutes a major environmental and human health concern worldwide. The aim of this study was to investigate the levels of POPs in irrigation water, soil and in Am ...

Effect of μM Fe addition, mild heat and solar UV on sulfate radical-mediated inactivation of bacteria, viruses, and micropollutant degradation in water

Luiz Felippe De Alencastro, César Pulgarin, Dominique Grandjean, Stefanos Giannakis, Miloch Marjanovic

In this work, solar disinfection (SODIS) was enhanced by moderate addition of Fe and sodium perox- ydisulfate (PDS), under solar light. A systematic assessment of the activating factors was performed, firstly isolated, then in pairs and concluded in the co ...

A green solar photo-Fenton process for the elimination of bacteria and micropollutants in municipal wastewater treatment using mineral iron and natural organic acids

César Pulgarin, Michaël Bensimon, Dominique Grandjean, Luiz Felippe De Alencastro, Sami Rtimi, Stefanos Giannakis, Paola Villegas Guzman

In this investigation, a new, green photo-Fenton process for wastewater treatment is proposed, involving the use of a natural iron source and natural additives, deriving from wastes, acting as iron chelators. The use of mineral iron as precursor in the pho ...

Solar photo-Fenton and UV/H2O2 processes against the antidepressant Venlafaxine in urban wastewaters and human urine. Intermediates formation and biodegradability assessment

Hubert Girault, César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Milica Jovic, Idriss Hendaoui

In this work, the use of Advanced Oxidation Processes (AOPs) against the degradation of an emerging contaminant has been subjected under systematic investigation. The optimization of treatment of the anti- depressant drug Venlafaxine (VFA) was performed, u ...

Micropollutant degradation, bacterial inactivation and regrowth risk in wastewater effluents: Influence of the secondary (pre)treatment on the efficiency of Advanced Oxidation Processes

César Pulgarin, Dominique Grandjean, Luiz Felippe De Alencastro, Stefanos Giannakis, Anoys Magnet

In this work, disinfection by 5 Advanced Oxidation Processes was preceded by 3 different secondary treatment systems present in the wastewater treatment plant of Vidy, Lausanne (Switzerland). 5 AOPs after two biological treatment methods (conventional acti ...

Evaluation of performance reference compounds (PRCs) to monitor emerging polar contaminants by polar organic chemical integrative samplers (POCIS) in rivers

Dominique Grandjean, Luiz Felippe De Alencastro, Nicolas Estoppey, Adrien Schopfer, Maria Inmaculada Carpinteiro Botana, Camille Fong

In this work, a method combining polar organic chemical integrative samplers (POCIS) and ultraperformance liquid chromatography coupled with tandem mass spectrometry (UPLC-MS/MS) was assessed for the determination of two corrosion inhibitors (benzotriazole ...

Evaluation of the risk to groundwater after treating logs with cypermethrin

Dominique Grandjean, Luiz Felippe De Alencastro, Dimitri Dousse

In order to protect conifer logs against attacks from the striped ambrosia beetle (Trypodendron lineatum ) during spring in Swiss forests, logs are treated with the insecticide cypermethrin. Rainfall can cause the insecticide to leach into the ground, pote ...
