Efficiency of micropollutant removal through artificial recharge and riverbank filtration: case studies of Káraný, Czech Republic and Dresden-Hosterwitz, Germany

Abstract

The aim of the study was to compare the e ciency of pharmaceuticals and personal care products (PPCP) removal in the waterworks Káraný (Czech Republic) and Dresden-Hosterwitz (Germany). Both waterworks use a similar technology of drinking water production (combination of bank ltration and arti cial recharge) and have similar river water quality (Jizera and Elbe river). A comparison of two-years monitoring results shows a high e ciency of removing PPCP contained in river water. However, at both waterworks there are groups of substances for which natural treatment steps alone are not su cient. In the case of Káraný it is Benzotriazole, Sulfamethoxazole and Methylparaben, in the Dresden waterworks it is Oxypurinol, Sulfamethoxazole, Carbamazepine and Lamotrigine.
