All the experimental part of this final project was done at Laboratoire de Biotechnologie
Environnementale (LBE) from the École Polytechnique Fédérale de Lausanne (EPFL),
Switzerland, during 6 months (November 2013- May 2014).
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 removal of two
micropollutants: the anti-inflammatory drug naproxen and the antibiotic sulfamethoxazole,.
Although Trametes versicolor was able to degrade quickly naproxen, this fungus was not any
more active after one week of operation in the filter. Pleurotus ostreatus was, on contrary,
able to survive more than 3 months in the filter, showing good removal efficiencies of
naproxen and sulfamethoxazole during all this period, in tap water but also in real treated
municipal wastewater.
Several other experiments have provided insight on the removal mechanisms of these
micropollutants in the fungal biofilter (degradation and adsorption) and also allowed to
model the removal trend.
Fungal treatment with Pleurotus ostreatus grown on wood substrates appeared to be a
promising solution to improve micropollutants removal in wastewater. |
