In this study, the main objective was to investigate the possibilities of the removal PPCPs (pharmaceuticals and personal care products) in the SBRs at the sludge ages of 20 and 10 days and at the two different temperatures 10°C and 20°C. The pharmaceuticals and personal care products can appear in the aquatic environment in several ways: via urine and faeces, by direct use of manure as fertilizer and also by inappropriate storage of the mentioned products. The obtained results showed, that the highest removal was gained for acidic compounds (ibuprofen, ketoprofen and naproxen). At the sludge age 20 d ibuprofen was degraded in above 90%, but at the sludge age 10 d, it was removed at the same level only at the temperature of 20°C. Moreover, it can be stated, that removal of some PPCPs shows strong correlation with sludge age. The following compounds showed higher removal at the longer sludge age: iopromide, DAMI, ibuprofen, bezafibrate, ketoprofen and pentoxifyllin. Furthermore, at the sludge age 10 d the emphatic correlation temperature – removal is observed for ibuprofen, ketoprofen and bezafibrate.

Głównym celem pracy było przeprowadzenie badań dotyczących możliwości usuwania substancji farmaceutycznych ze ścieków przy użyciu reaktora typu SBR o różnych wiekach osadu czynnego (10 i 20 d) w temperaturze 10°C i 20°C. Największą podatność na degradację uzyskano dla ibuprofenu, ketoprofenu i naproxenu. Przy wieku osadu równym 20 d usunięcie ibuprofenu przekraczało 90% w obu badanych temperaturach, natomiast przy wieku osadu równym 10 d, ten sam poziom usunięcia otrzymano w temperaturze 20°C. Stwierdzono, że usunięcie niektórych badanych substancji farmaceutycznych (iopromid, DAMI, ibuprofen, bezafibrat, ketoprofen i pentoxifyllina) jest zależne od wieku osadu. Dodatkowo, przy wieku osadu 10 d wykazano zależność między eliminacją substancji farmaceutycznych (ibuprofen, ketoprofen, i bezafibrat) a temperaturą prowadzenia procesu.
