The study assesses the removal of a broad range of pharmaceutical compounds through an integrated system of membrane bioreactors and reverse osmosis (MBR-RO) at pilot plant scale. MBR technology combines biological degradation of pollutants with physical separation of water through filtration. When this technology is integrated with a reverse osmosis unit, the filtration of the effluent – already treated in MBR – is more exhaustive, with a smaller pore size. Results show that the combination of MBR and RO technologies leads to the removal of up to 99% of pharmaceutical compounds, which constitutes a significant improvement to current urban wastewater treatment technologies.
