Forward osmosis (FO) is a promising technol. for the treatment of urban wastewater. FO can produce high-quality effluents and preconc. urban wastewater for subsequent anaerobic treatment. This membrane technol. makes it possible to eliminate the pollutants present in urban wastewater, which can cause adverse effects in the ecosystem even at low concentrations In this study, a 0.6 m2 hollow fiber aquaporin forward osmosis membrane was used for the treatment of urban wastewater from the Valladolid wastewater treatment plant (WWTP). A total of 51 Contaminants of Emerging Concern (CECs) were investigated, of which 18 were found in the target urban wastewater. They were quantified, and their ecotoxicol. risk impact was evaluated. Different salts with different concentrations were tested as draw solutions to evaluate the membrane performances when working with pretreated urban wastewater. NaCl was found to be the most appropriate salt since it leads to higher permeate fluxes and lower reverse saline fluxes. The membrane can eliminate or significantly reduce the pollutants present in the studied urban wastewater, producing water without ecotoxicol. risk or essentially free of pollutants. In all cases, good recovery was achieved, which increased with mol. weight, although chem. and electrostatic interactions also played a role.
