Many chems. with different physico-chem. properties are present in municipal wastewater. In this study, the removal of a broad range of trace organic chems. (TOrCs) was determined in two biol. treatment processes differing in hydraulic retention time: sequential biofiltration (SBF) and soil-aquifer treatment (SAT), operated in Germany and Spain. Occurrence and the degree of removal of more than 150 TOrCs with different physico-chem. properties were analyzed, including precursors as well as human metabolites and environmental transformation products (TPs). Ninety TOrCs were detected in the feed water of the SBF system, 40% of these showed removal efficiencies of higher than 30% during biol. treatment. In SAT, 70 TOrCs were detected in the feed water, 60% of these could be reduced by more than 30% after approx. 3 days of subsurface treatment. For uncharged and neg. charged TOrCs biol. degradation was mainly responsible for the removal, while pos. charged TOrCs were most likely also removed by ionic interactions. The detections of TPs confirmed that biodegradation was a major removal process in both systems. The anal. of pos. and neg. charged, neutral and zwitterionic TOrCs and the simultaneous anal. of precursors and their biol. formed TPs enabled a detailed understanding of underlying mechanisms of their removal in the two systems. On this basis, criteria for site-specific indicator selection were proposed.
