Behavior of Organic Micropollutants During River Bank Filtration in Budapest, Hungary

A six-month study in Budapest revealed that river bank filtration significantly reduces concentrations of certain organic micropollutants, with some compounds showing up to 78% removal efficiency. Bisphenol A, carbamazepine, and sulfamethoxazole exhibited minimal reduction (<20%), while others like 1H-benzotriazole and diclofenac demonstrated substantial attenuation during filtration on Szentendre Island and Csepel Island. The research analyzed 36 emerging micropollutants in Danube River water and bank filtrate, highlighting the potential of this natural process to improve water quality by lowering pollutant levels.
