A pilot project shows that the combination of membrane bioreactors (MBR) and reverse osmosis (RO) leads to the removal of more than 99% pharmaceutical products in wastewaters

The experiments were carried out at the wastewater treatment plant of Castell-Platja d’Aro within the framework of a cooperation project between Institut Català de Recerca de l’Aigua (ICRA), Laboratori d’Enginyeria Química i Ambiental de la UdG (LEQUIA), Consorci Costa Brava (CCB) and Empresa Mixta d’Aigües de la Costa Brava S.A.

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.

The autors of the study are Davor Dolar, Meritxell Gros, Sara Rodríguez-Mozaz, Jordi Moreno, Joaquim Comas, Ignasi Rodríguez-Roda and Damià Barceló.
