“…Removal efficiencies greater than 90% for naproxen and ibuprofen have been reported for a WWTP that uses UV for disinfection; however, the same plant did not show any removal for diclofenac (Carmona et al, 2014). Poor removal of diclofenac has been reported for a number of WWTPs (Lindqvist et al, 2005;Rosal et al, 2010;Zorita et al, 2009;Samaras et al, 2013). Further work is required in order to investigate the effect of poor removal and to rectify the problem for diclofenac.…”

“…After use, most of the PCPs containing TCS are washed down the drain and discharged into wastewater treatment plants (WWTPs), with its reported removal efficiencies of 57-99 % (Bester 2005;Halden 2014;Samaras et al 2013;Singer et al 2002;Thomas and Foster 2005;Wick et al 2010;, and eventually into the receiving aquatic environment (Halden 2014). The large consumption for TCS has promoted it to be ranked in the list of top contaminants of concern worldwide (von der Ohe et al 2012).…”

This study aimed to investigate the emission and multimedia fate as well as potential risks of triclosan (TCS) in all of 58 basins in China. The results showed that the total usage of TCS in whole China was 100 t/year, and the discharge to the receiving environment was estimated to be 66.1 t/year. The predicted TCS concentrations by the level III fugacity model were within an order of magnitude of the reported measured concentrations. TCS (90.8 %) was discharged into the water compartment and 9.2 % to the soil compartment. The TCS concentration levels in east China were found generally higher than in west China. In addition, the input flux for TCS to seawater was largely attributed to the seasonal variations in advection flows. Preliminary risk assessment showed that medium to high ecological risks for TCS would be expected in the eastern part of China due to the high population density.

“…As for the removal of TCS during ADs, there also existed big differences among the previous studies. Samaras et al (2013) investigated several PhACs in the two full-scale STPs of Greece and found the removal rate of TCS using the mesophilic AD was about 22 %. Higher removal rates (30-50 %) were obtained by Narumiya et al (2013) who conducted the survey of the fate of pharmaceuticals and personal products (PPCPs) including TCS during the mesophilic and thermophilic ADs in the four full-scale STPs.…”

“…The thermophilic treatment is also increasingly introduced because of the increased demands on sewage sludge treatment and reduction (Merrylin et al 2013). Although in recent researches, Narumiya et al (2013) and Samaras et al (2013) reported the fate and removal of some pharmaceuticals during mesophilic and/or thermophilic ADs of sewage sludge in full-scale STPs; there is still very limited information about the variations and removal of PhACs during the processes.…”

The removal of four pharmaceutically active compounds, i.e., anti-inflammatory painkiller diclofenac (DCF), lipid-regulating agent clofibric acid (CFA), epilepsy drugs carbamazepine (CBM), and broad-spectrum anti-bacterial agent triclosan (TCS), present in sewage sludge was investigated using anaerobic digestion processes in the mesophilic and thermophilic modes. Sludge retention times (SRTs) were set at 10, 15, and 20 days, respectively, for the mesophilic mode and 7, 15, and 20 days, respectively, for the thermophilic mode. The effective isolation and purification pre-treatment to extract the target compounds from the sewage sludge samples were firstly established, followed by gas chromatographymass spectrometer analysis to identify and quantify them. The removal efficiencies of the target compounds could be raised to a certain extent with the increase on SRTs, especially under the mesophilic condition. The removal of CFA and TCS under thermophilic condition hardly varied when the SRTs were above 15 days. All the compounds could be partly removed from the sewage sludge under the two temperature conditions, particularly TCS that was reduced by about 74 %. Besides, CFA, firstly reported in this study, could be reduced by maximal 65 %. On the whole, the thermophilic mode was more conducive to the removal of CBM and TCS, but did not have a noticeable effect on the removal of CFA. Furthermore, DCF could be better removed in the mesophilic mode. In addition, NH 3 -N accumulation in this measured range might positively affect the removal of the selected compounds, particularly in the mesophilic mode.
