Treatment of micropollutants in municipal wastewater: study of a sequential batch biofilter

Andreu Contijoch Culleré

A fungal biofilter composed of woodchips was designed in order to remove micropollutants from the effluents of waste water treatment plants. Two fungi were tested: Pleurotus ostreatus and Trametes versicolor in order to evaluate their efficiency for the re ...

Micropollutant dynamics in Vidy Bay - A coupled hydrodynamic-photolysis model to assess the spatial extent of ecotoxicological risk

David Andrew Barry, Tamar Kohn, Florence Bonvin, Amir Mehdi Razmi

The direct discharge of effluent wastewater into Vidy Bay (Lake Geneva) results in the formation of an effluent plume with locally high concentrations of wastewater-derived micropollutants. The micropollutant hotspots above the wastewater outfall present a ...

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 ...
