NanoSTEP : Impact of Engineered Nanomaterial on wastewater treatment and biosolids valorization
The increasing use of Engineered Nanomaterials (ENMs) by industry and consumers,
lead to their release into the environment. An important route of exposure
is through the waste stream, where ENMs will enter wastewater treatment plants
(WWTPs), undergo transformations, and be discharged with treated effluent or
biosolids. In the NanoSTEP project, we propose to decipher whether ENMs will be efficiently treated in WWTPs, whether they will disturb the treatment of others pollutants (e.g. viruses, organics), whether they will impact the valorization pathways of the biosolids (energetic or agronomic valorization). To better understand the fate and impacts in WWTPs of ENMs and residues of degradation of products containing ENMs, experiments
with laboratory-scale bioreactors are conducted.
