A PILOT PROJECT WITH REVERSE OSMOSIS FILTRATION

A PILOT PROJECT DEMONSTRATED THAT REVERSE OSMOSIS FILTRATION ELIMINATES OVER 99% OF DRUG DEPOSITED IN THE WWTP

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

The combination of MBR and RO treatment has shown excellent efficacy in eliminating the drug, which allowed removing over 99% of all cases.

The presence of emerging contaminants such as pharmaceuticals in the aquatic environment and their effects on living organisms has become an issue of growing concern for scientists, water managers and the public.

A pilot project conducted at Station Wastewater Treatment Plant (WWTP) Castell-Platja d'Aro proves the efficiency of removal of pharmaceuticals are considered emerging contaminants from wastewater using a system that includes a bioreactor membrane combined with a reverse osmosis system (MBR-RO).

The project was carried out by the Catalan Institute for Water Research (ICRA), Laboratory of Chemical and Environmental Engineering of the University of Girona (LEQUIA), the Consortium of Costa Brava (CCB) and the Joint Company Waters of the Costa Brava, SA.
