AB  - Triclosan (TCS) as an antimicrobial agent has been ubiquitously found in 
      wastewater and sewage sludge. TCS may undergo transformation/degradation during 
      wastewater treatment. Some of the resulted products such as 2,4-dichlorophenol 
      (2,4-DCP), 2,8-dichlorodibenzoparadioxin (2,8-DCDD) and methyl triclosan (MTCS) 
      are presumed toxic/persistent compounds. In this study, fate of TCS and the 
      probability of formation of important degradation products were investigated in 
      three susceptible wastewater/sludge treatment practices. 24.1% and 27.2% of the 
      loading TCS was adsorbed to the generated sludge, whereas up to 60% of the 
      loading TCS was biotransformed. Up to 9.9% and 13.0% of TCS loss was attributed 
      to the formation of 2,4-DCP and 2,8-DCDD in chlorination and UV disinfection, 
      respectively. Anaerobic and aerobic sludge digestion processes eliminated up to 
      23.0% and 56.0% of TCS, respectively. About 7.4% of TCS in aerobic digestion was 
      transformed to methyl triclosan (MTCS). Significant temporal variation of TCS was 
      observed in primary sedimentations, except for chemically enhanced primary 
      treatment that was suggested to be governed by chemical-forced sedimentation. 
      Distribution coefficient (K(d)) of TCS was directly correlated to the total 
      organic carbon of the sludge (TOC). Moreover, strong correlation was observed 
      between elimination efficiency in primary sedimentation and loading 
      concentration.
