“…In this context, N 2 O emissions from wastewater treatment has received increasing attention in recent years (Kampschreur et al, 2009;Law et al, 2012;Mannina et al, 2016a). Specifically, N 2 O generation mainly occurs in biological nitrogen removal (BNR) (Cosenza et al, 2013) via nitrification and denitrification processes as both autotrophic and heterotrophic bacteria can be responsible for N 2 O production during BNR (Kampschreur et al, 2009). …”

“…During nitrification, N 2 O may be produced by ammonia oxidizing bacteria (AOB) (Peng et al, 2014 originating via two main pathways (Kampschreur et al, 2009): (1) the reduction of NO 2 À as terminal electron acceptor to N 2 O (AOB denitrification) (Kim et al, 2010;Yu et al, 2010;Wrage et al, 2001;Stuven et al, 1992); (2) incomplete oxidation of hydroxylamine (NH 2 OH) to NO 2 À (Law et al, 2012;Chandran et al, 2011).…”

“…In the last years, many efforts have been devoted towards the understanding of the key mechanisms involved in N 2 O production and emission (Kampschreur et al, 2009;Quan et al, 2012;Rodriguez-Caballero and Pijuan, 2013;Stenstr€ om et al, 2014;Wu et al, 2014;Hwang et al, 2016;Mannina et al, 2016c). 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.

“…The important factors influencing the increase of N 2 O were (i) low dissolved oxygen (DO) concentration in nitrification, (ii) higher nitrate concentration in nitrification/ denitrification process, and (iii) low COD/N ratio (Kampschreur et al, 2009). N 2 O was believed to contribute for more than 90% of total GWP in the treatment (Préndez and Lara-González, 2008).…”

A mini-review on the impacts of climate change on wastewater reclamation and reuse

To tackle current water insecurity concerns, wastewater reclamation and reuse has appeared as a promising candidate to conserve the valuable fresh water sources whilst increasing the efficiency of material utilization. The climate change, nevertheless, poses both opportunities and threats to the wastewater reclamation industry. Whereas it elevates the social perception on water-related issues and fosters an emerging water-reuse market, the climate change simultaneously presents adverse impacts on the water reclamation scheme, either directly or indirectly. These effects were studied fragmentally in separate realms. Hence, this paper aims to link these studies for providing a thorough understanding about the consequences of the climate change on the wastewater reclamation and reuse. It initially summarizes contemporary treatment processes and their reuse purposes before carrying out a systematic analysis of available findings.

Regional‐scale controls on dissolved nitrous oxide in the Upper Mississippi River

The U.S. Corn Belt is one of the most intensive agricultural regions of the world and is drained by the Upper Mississippi River (UMR), which forms one of the largest drainage basins in the U.S. While the effects of agricultural nitrate (NO3−) on water quality in the UMR have been well documented, its impact on the production of nitrous oxide (N2O) has not been reported. Using a novel equilibration technique, we present the largest data set of freshwater dissolved N2O concentrations (0.7 to 6 times saturation) and examine the controls on its variability over a 350 km reach of the UMR. Driven by a supersaturated water column, the UMR was an important atmospheric N2O source (+68 mg N2O N m−2 yr−1) that varies nonlinearly with the NO3− concentration. Our analyses indicated that a projected doubling of the NO3− concentration by 2050 would cause dissolved N2O concentrations and emissions to increase by about 40%.
