Current wastewater treatment is not designed to eliminate micropollutants (MP) such as pharmaceuticals, pesticides, and microplastics, which is why they enter surface waters via municipal wastewater. A combination of a fixed-bed reactor (FBR) and nanofiltration (NF) was implemented to eliminate MP. The NF acts as a barrier to MP, while biodegradation of the pollutants is induced in the FBR. The experiments show that NF can separate on average more than 93% of MP. Except for two problematic substances, the average biodegradation rate in the FBR was 78%. With a combination plant of NF and FBR, the spectral absorption coefficient SAK270 could be eliminated to 89 %, and this parameter is considered to be of great significance with regard to the amount of MP and their metabolites.
