The two key processes for transformation and, ultimately, removal of N from wastewater are nitrification and denitrification. 39 During denitrification, nitrate is reduced to nitrogen gas under anoxic conditions, thus completely removing N from the system. 2. 22,42 (Figure 3), indicated that, in general, Beenyup WWTP has good nitrification (ammonia < 2 mg/L-N) and partial denitrification (nitrate > 5 mg/L-N). 43 To investigate the effect of nitrification and denitrification on NDMA precursor removal at Beenyup WWTP, matched primary and secondary wastewater were collected over a variety of different flow rates in two separate sampling campaigns, and a variety of N species, as well as NDMA precursors, were measured (Table 2).

Ten microliters of the extract were diluted in 10 mL of EtOAc. 1). 4 GC-MSn analysis The analyses were performed with an Agilent Technologies 7890A gas chromatograph (GC) coupled to an Agilent Technologies ion trap 240 mass spectrometer (MS) (Palo alto, CA, USA). SPME extractions were automated by using a GC autosampler 120 from Agilent Technologies. 3 mL/min. 25 μm film thickness) purchased from Restek (Lisses, France). 7 min. MS was operated in external electron impact. The source, ion trap, transfer line and manifold temperatures were 250 °C, 200 °C, 320 °C and 50 °C respectively.
