Fate and removal of typical pharmaceuticals and personal care products by three different treatment processes

► We investigated 8 kinds of pharmaceuticals and personal care products in each unit at 2 wastewater treatment plants with different processes. ► Agilent 1290–6460 HPLC–MS/MS was firstly utilized to detect estrogens. ► More hydrophobic estrogens such as EE2 and E2 had a higher removal efficiency. ► The OD system was less efficient than anaerobic/oxic process and A/A/O-MBR processes in estrogen removal. ► The estrogen removal in anaerobic units was less efficient than that under aerobic conditions

Scholarcy highlights

  • The presence and distribution of typical of pharmaceuticals and personal care products, which comprise two types of polycyclic musks including Galaxolide and Tonalide as well as six types of estrogens containing estrone, 17β-estradiol, estriol, 17α-ethynylestradiol, diethylstilbestrol, and bisphenol A, were investigated at two wastewater treatment plants in Jiangsu, China
  • Raw wastewater was treated in WWTP A while WWTP B was serving an urban-industrialized area
  • The concentrations of EE2, E2, and DES were generally higher than the previously reported values, whereas the concentrations of HHCB, E1, E3, and BPA were much lower than those reported in other previous studies
  • The removal efficiencies for estrogens in biological processes were related to the following factors: the level of hydrophobic estrogens, the type of removal process, and a high sludge retention time or hydraulic retention time
  • ► We investigated 8 kinds of PPCPs in each unit at 2 WWTPs with different processes. ► Agilent 1290–6460 HPLC–MS/MS was firstly utilized to detect estrogens. ► More hydrophobic estrogens such as EE2 and E2 had a higher removal efficiency. ► The OD system was less efficient than A/O and A/A/O-MBR processes in estrogen removal. ► The estrogen removal in anaerobic units was less efficient than that under aerobic conditions
