“…Pilot-scale reactors have demonstrated consistent results with SMX removal rates ranging from 52 to 70 % regardless of initial SMX concentration (145 ng/L to 20 μg/L) (Clara et al 2005;Kim et al 2007;Reif et al 2008). Lab-scale MBR studies (9 and 14 L) have demonstrated SMX degradation as a function of pH and powdered activated carbon (PAC) dose.…”

Antibiotic compounds, like sulfamethoxazole (SMX), have become a concern in the aquatic environment due to the potential development of antibacterial resistances. Due to extensive consumption, excretion and disposal, SMX has been frequently detected in wastewaters and surface waters. This has led to numerous studies investigating the nature of SMX, with many researchers focusing on the biodegradation and persistence of SMX during wastewater treatment and in the environment. This review provides a summary of recent developments, outlines the discrepancies in observations and results, and demonstrates the need for further research to determine optimal biological removal strategies for SMX and other antibiotics.

“…In general, OD usually uses the extended aeration, which has a long SRT (20-40 days); Due to its big and batch reactor, SBR often operates with the SRT of 15-25 days; AAO usually operates with the SRT of 10-20 days; With the relatively simple process, AO possesses the relative short SRT (3-10 days). As an important parameter for activated sludge process design and operation (Batt et al, 2007;Clara et al, 2005), SRT may influence the levels of antibiotics in sludge.…”

“…MBR outperforms the conventional activated sludge process (CAS) in many aspects including better effluent quality, smaller physical footprint, and lower sludge production (Melin et al, 2006). Because MBR technology is well-suited for water recycling applications, considerable research efforts have been devoted to the assessment of trace organic contaminants removal by MBR treatment (Clara et al, 2005;Joss et al, 2005;Kimura et al, 2007). These contaminants occur ubiquitously in domestic and industrial wastewater (Basile et al, 2011).…”

“…Their presence in reclaimed water used for indirect potable recycling application even at very low concentration ranging from several ng/L to a few µg/L may present a potential ecotoxicological risk (Alexander et al, 2012). In comparison to CAS, MBR has been reported to show relatively better and/or more stable removal of trace organic contaminants possessing moderate to high biodegradability (Clara et al, 2005;De Wever et al, 2007). Although the effectiveness of MBR treatment for eliminating trace organic contaminants has been well demonstrated in the literature, recent studies have also shown the limitation of MBR in removing certain persistent compounds (Clara et al, 2005;Joss et al, 2005;Tadkaew et al, 2011).…”

Therefore, it is necessary to implement a post-treatment process after MBR particularly in indirect potable water recycling applications or when discharging the effluent to an ecologically sensitive environment.…”

Coupling granular activated carbon adsorption with membrane bioreactor treatment for trace organic contaminant removal: Breakthrough behaviour of persistent and hydrophilic compounds. Journal of Environmental Management, 119 173-181.Coupling granular activated carbon adsorption with membrane bioreactor treatment for trace organic contaminant removal: Breakthrough behaviour of persistent and hydrophilic compounds AbstractThis study investigated the removal of trace organic contaminants by a combined membrane bioreactorgranular activated carbon (MBR-GAC) system over a period of 196 days. Of the 22 compounds investigated here, all six hydrophilic compounds with electron-withdrawing functional groups (i.e., metronidazole, carbamazepine, ketoprofen, naproxen, fenoprop and diclofenac) exhibited very low removal efficiency by MBR-only treatment. GAC post-treatment initially complemented MBR treatment very well; however, a compound-specific gradual deterioration of the removal of the above-mentioned problematic compounds was noted. While a 20% breakthrough of all four negatively charged compounds namely ketoprofen, naproxen, fenoprop and diclofenac occurred within 1000-3000 bed volumes (BV), the same level of breakthrough of the two neutral compounds metronidazole and carbamazepine did not occur until 11,000 BV. Single-solute isotherm parameters did not demonstrate any discernible correlation individually with any of the parameters that may govern adsorption onto GAC, such as log D, number of hydrogen-bond donor/acceptor groups, dipole moment or aromaticity ratio of the compounds. The isotherm data, however, could differentiate the breakthrough behaviour between negatively charged and neutral trace organic contaminants. © 2013 Elsevier Ltd.
