“…This method has often been used in previous studies to determine CH 4 from landfills and more recently WWTPs (Czepiel et al, 1996;Galle et al, 2001;Spokas et al, 2006;Fredenslund et al, 2010;Mønster et al, 2014b;Yoshida et al, 2014). Concentrations of the tracer as well as the gas of interest are measured using a mobile instrument downwind in the co-propagating plumes.…”

“…Cakir and Stenstrom (2005) and El-Fadel and Massoud (2001) present estimations based on process modeling, but some studies such as Czepiel et al (1993), Wang et al (2011) and Daelman et al (2012) calculate emissions using CH 4 measurements with mass budget. Finally, a recent study by Yoshida et al (2014) used the tracer release method as described in this paper to estimate CH 4 and N 2 O emissions from a WWTP. In these papers, emissions vary from 0.011 to 1.3 kg yr −1 per population equivalent depending on the WWTP design (e.g., depending on the use of aerobic or anaerobic processes, presence of a sludge digester) and the estimation method as the tracer release allows the capturing of leakage emissions that could be omitted by the other methods.…”

Abstract. This study presents two methods for estimating methane emissions from a waste water treatment plant (WWTP) along with results from a measurement campaign at a WWTP in Valence, France. These methods, chamber measurements and tracer release, rely on Fourier transform infrared spectroscopy and cavity ring-down spectroscopy instruments. We show that the tracer release method is suitable for quantifying facility-and some process-scale emissions, while the chamber measurements provide insight into individual process emissions. Uncertainties for the two methods are described and discussed. Applying the methods to CH 4 emissions of the WWTP, we confirm that the open basins are not a major source of CH 4 on the WWTP (about 10 % of the total emissions), but that the pretreatment and sludge treatment are the main emitters. Overall, the waste water treatment plant is representative of an average French WWTP.

“…This allowed for an accurate estimate of the complete amount of nitrous oxide that is emitted from the reactors to the atmosphere. In contrast, Yoshida et al (2014) used emission plume measurements from an open plant, while all the other studies mentioned in Table 1 used floating hoods. These floating hoods only measure the emission from a small surface and those measurements may therefore not be representative of the total emission of an entire reactor, given the emission's spatial variability.…”

“…The reported studies demonstrated a huge variability of the N 2 O emission (from the 0.01% to 10% of the influent total nitrogen) (Yoshida et al, 2014), depending on the WWTPs operational conditions (Kampschreur et al, 2009;Law et al, 2012;Daelman et al, 2013). Moreover, the technical literature shows that in processes aimed at the simultaneous nitrogen and phosphorous removal (SNPR), the role of polyphosphate accumulating organisms (PAOs) in the production of N 2 O cannot be disregarded (among others, Zhou et al, 2012).…”

a b s t r a c tThe present paper reports the results of a nitrous oxide (N 2 O) production investigation in a moving bed based integrated fixed film activated sludge (IFAS) membrane bioreactor (MBR) pilot plant designed in accordance with the University of Cape Town layout for biological phosphorous removal. Gaseous and liquid samples were collected in order to measure the gaseous as well as the dissolved concentration of N 2 O. Furthermore, the gas flow rate from each reactor was measured and the gas flux was estimated. The results confirmed that the anoxic reactor represents the main source of nitrous oxide production. A significant production of N 2 O was, however, also found in the anaerobic reactor, thus indicating a probable occurrence of the denitrifying phosphate accumulating organism activity. The highest N 2 O fluxes were emitted from the aerated reactors (3.09 g N 2 OeN m À2 h À1 and 9.87 g N 2 OeN m À2 h À1 , aerobic and MBR tank, respectively). The emission factor highlighted that only 1% of the total treated nitrogen was emitted from the pilot plant. Furthermore, the measured N 2 O concentrations in the permeate flow were comparable with other reactors. Nitrous oxide mass balances outlined a moderate production also in the MBR reactor despite the low hydraulic retention time. On the other hand, the mass balance showed that in the aerobic reactor a constant consumption of nitrous oxide (up to almost 15 mg N 2 O h À1 ) took place, due to the high amount of stripped gas.
