Phase distribution and removal of pharmaceuticals and personal care products during anaerobic sludge digestion

- The fate of 48 PPCPs during anaerobic sludge digestion was investigated in STPs.
- We measured concentrations of PPCPs in both the liquid and solid phases of sludge.
- Several antimicrobial compounds remained in digested sludge at mg/kg-dry level.
- The distribution of selected PPCPs between the two phases changed during digestion.
- Triclosan and triclocarban were moderately degraded, while carbamazepine was not.
