TLDR
It is shown that short-term sampling is inadequate to accurately estimate the average nitrous oxide emissions from a particular wastewater treatment plant, while online monitoring is indispensable to capture the short- term variability (diurnal dynamics).About:

A review on nitrous oxide (N2O) emissions during biological nutrient removal from municipal wastewater and sludge reject water.
Theoni Maria Massara,Simos Malamis,Albert Guisasola,Juan A. Baeza,Constantinos Noutsopoulos,Evina Katsou +5 more
TL;DR: A critical review of the existing literature on N2O emissions during BNR is presented focusing on the most contributing parameters, with an undeniable validation of the robustness of such models calls for reliable quantification techniques which simultaneously describe dissolved and gaseous N 2O dynamics.

TL;DR: Simulation results highlight the potential undesirable effects of increased GHG production when carrying out local energy optimization of the aeration system in the activated sludge section and energy recovery from the AD.

Effect of aeration regime on N2O emission from partial nitritation-anammox in a full-scale granular sludge reactor
C.M. Castro-Barros,Matthijs R.J. Daelman,Matthijs R.J. Daelman,K. E. Mampaey,M.C.M. van Loosdrecht,Eveline Volcke +5 more
TL;DR: Investigation of the N₂O emission dynamics in a full-scale one-stage granular sludge reactor performing partial nitritation-anammox (PNA) operated at a N-loading of 1.75 kg NH₄⁺-N m⁻³ d⁽¹ indicates that adequate aeration control may be used to minimize N⁂O emissions from PNA reactors.
Journal ArticleDOI
Plant-integrated measurement of greenhouse gas emissions from a municipal wastewater treatment plant
TL;DR: The application of a tracer dispersion method to quantify plant-integrated, real-time emissions of methane and nitrous oxides from WWTPs shows that the unit process configuration, as well as the operation of the WWTP, determines the rate of GHG emission.
Journal ArticleDOI
Seasonal and diurnal variability of N2O emissions from a full-scale municipal wastewater treatment plant.

TL;DR: The diurnal Trend of the emission coincided with the diurnal trend of the nitrite and nitrate concentrations in the tank, suggesting that suboptimal oxygen concentrations may induce the production of nitrous oxide during both nitrification and denitrification.

TL;DR: Analysis of literature data enabled the identification of the most important operational parameters leading to N(2)O emission in WWTPs: (i) low dissolved oxygen concentration in the nitrification and denitrification stages, (ii) increased nitrite concentrations in both nitrified stages, and (iii) low COD/N ratio in theDenitrification stage.

TL;DR: It seems that a low dissolved oxygen or a high nitrite concentration are the most likely cause of elevated NO and N2O emission by ammonia-oxidizing bacteria.

TL;DR: It is demonstrated that sampling errors can lead to overinterpretation of measured data and ultimately, wrong conclusions.

Nitrous oxide emissions from wastewater treatment processes
TL;DR: With increased understanding of the fundamental reactions responsible for N 2O production in wastewater treatment systems and the conditions that stimulate their occurrence, reduction of N2O emissions from wastewater treatment plants through improved plant design and operation will be achieved in the near future.

Nitrous oxide generation in full-scale biological nutrient removal wastewater treatment plants
TL;DR: N(2)O formation was shown to be always positive, yet highly variable across the seven full-scale BNR wastewater treatment plants (WWTP), but with many competing and parallel nitrogen transformation reactions occurring, it was very difficult to clearly identify the predominant mechanism of N( 2)O production.
