Temporal evolution in PPCP removal from urban wastewater by constructed wetlands of different configuration: A medium-term study

► The medium-term behaviour of constructed wetlands (CWs) to remove PPCPs was assessed. ► Removal efficiencies decreased throughout the operational time. ► Performance differences among several types of CWs softened throughout time. ► Winter removal efficiencies were lower than summer ones for many PPCPs. ► Carbamazepine and diclofenac were partially removed.
