The sludge retention time (SRT) is the most important parameter for the design of wastewater treatment plants. To study the influence of this design parameter on the elimination of selected pharmaceuticals lab scale experiments with different SRT (1 d, 12-15 d and 30 d) were performed. Common pharmaceuticals for different applications, in particular two antibiotics (Roxythromycin, Sulfamethoxazole), two analgesics/antiphlogistics (Diclofenac, Ibuprofen), the antiepileptic Carbamazepine, the contrast media Iopromide, the tra
