“…Cytostatic drugs and their metabolites enter the aquatic environment mainly through excretion of urine and feces of patients undergoing chemotherapy (Köhler et al, 2012;Zounkova et al, 2010). Hospital effluents are rarely pretreated prior to their discharge into the public sewer system and are thereby considered potential hotspots (Zhang et al, 2013).…”

“…On the other hand, little is known about the complementarity between MBR treatment and other advanced treatment processes including UV oxidation or NF/RO membrane filtrations with respect to the removal of TrOC. To date, there have been only a very few studies on the application of integrated MBR-UV oxidation treatment process for the removal of TrOC (Laera et al, 2011, Köhler et al, 2012 and MBR-NF/RO membrane filtration (Alturki et al, 2010).…”

The aim of this study was to demonstrate the complementarity of combining membrane bioreactor (MBR) treatment with UV oxidation or high pressure membrane filtration processes such as nanofiltration (NF) or reverse osmosis (RO) for the removal of trace organic contaminants (TrOC). The results suggest that the removal mechanisms of TrOC by either UV oxidation or NF/RO membrane filtration differ significantly from those of an MBR system. Thus, they can complement MBR treatment very well to significantly improve the removal of TrOC. MBR treatment can effectively remove hydrophobic and readily biodegradable hydrophilic TrOC. The remaining hydrophilic and biologically persistent TrOC were shown to be effectively removed by either UV oxidation or NF/RO membrane filtration. The combination of MBR with UV oxidation or NF/RO membrane filtration resulted in a removal ranging from 85% to complete removal (or removal to below the analytical detection limit) of all 22 TrOC selected in this study. In particular, it is noteworthy that although MBR treatment and direct UV oxidation separately achieved low removal of carbamazepine (a widely reported problematic compound), the combination of these two processes resulted in more than 96% removal. RESEARCH HIGHLIGHTS:• MBR, UV oxidation, and NF/RO membranes remove TrOC based on different mechanisms.• MBR could effectively remove hydrophobic and readily biodegradable TrOC.• Chlorinated TrOC and TrOC with a phenolic group are readily degraded by UV oxidation.• NF/RO membranes can effectively reject charged and hydrophilic TrOC.• Thus, MBR-UV or MBR-NF/RO hybrid systems are very effective for removing TrOC.2 AbstractThe aim of this study was to demonstrate the complementarity of combining membrane bioreactor (MBR) treatment with UV oxidation or high pressure membrane filtration processes such as nanofiltration (NF) or reverse osmosis (RO) for the removal of trace organic contaminants (TrOC).

Of particular interest was the fact that although MBR treatment and direct UV oxidation separately both achieved low removal of carbamazepine (a widely reported problematic compound), the combination of these two processes resulted in more than 96%removal.

“…Literature review reveals inconsistent removal efficiencies for CP and IF (0-72%) by biological treatment (Buerge et al, 2006;Delgado et al, 2011;Kiffmeyer et al, 1998;Kovalova et al, 2012;Köhler et al, 2012;Kümmerer et al, 1997Kümmerer et al, , 2000Steger-Hartmann et al, 1997). Amongst them only Kovalova et al (2012), Köhler et al (2012) and Delgado et al (2011) used a non-conventional biological treatment by applying membrane bioreactors. Kovalova et al (2012) and Köhler et al (2012), who used hospital wastewater as a matrix, were able to remove 20% and 12% of CP, respectively, while Delgado et al (2011) removed 80% of CP from an artificial wastewater.…”
