Abstract: The purpose of this study was to investigate the fate of three tetracyclines (TCs), namely oxytetracycline (OTC), chlortetracycline (CTC) and doxycycline (DC) at two different full-scale swine manure-activated sludge treatment plants. Throughout treatment, OTC, CTC and DC were removed by 71-76%, 75-80% and 95%, respectively. Removal of these TCs under physical treatment was deniable. On the contrary, the flocculation-coagulation and the secondary clarification resulted in a relevant reduction of the concentration of these TCs.
