Ozonation of municipal wastewater effluent containing metal sulfides and metal complexes: Kinetics and mechanisms

Urs von Gunten

Ozonation can be applied to mitigate the discharge of organic micropollutants from municipal wastewater treatment plants (WWTPs) to the aquatic environment. The toxicity of metals also present in WWTP effluents strongly depends on their speciation. Therefo ...

Modeling Hydraulic Transport and Anaerobic Uptake by PAOs and GAOs During Wastewater Feeding in EBPR Granular Sludge Reactors

Christof Holliger, David Gregory Weissbrodt

New-generation bioprocesses using granular sludge aim for a high-rate removal of nutrients from wastewater with low footprint. Achieving enhanced biological phosphorus removal (EBPR) relies on the design of sludge beds and wastewater feeding conditions to ...

VUV/UV light inducing accelerated phenol degradation with a low electric input

Juan Kiwi, Mengkai Li

This study presents the first evidence for the accelerated degradation of phenol by Fenton's reagent in a minifluidic VUV/UV photoreaction system (MVPS). A low-pressure mercury lamp used in the MVPS led to a complete degradation of phenol within 4-6 min. T ...

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 ...

Validation of Landsat-8 and Sentinel-2 algorithms for atmospheric correction on Lake Geneva

Sonia Joëlle Dupuis

Remote-sensing of water surfaces such as large lakes is a useful tool for monitoring and understanding large-scale processes. Suspended particles in lakes can have various sources such as autochthonously produced organic matter, urban or agricultural runof ...
