Release of nitrous oxide (N2O) from denitrifying activated sludge: Verification and application of a mathematical model
TLDR
In this paper, the authors extended Schulthess et al.'s model with the consumption of organic substrate and with nitrification to predict the nitrous oxide (N2O) accumulation in continuously fed full scale waste water treatment plants.About:

Nitrous oxide emission during wastewater treatment.
Marlies J. Kampschreur,Hardy Temmink,Robbert Kleerebezem,Mike S. M. Jetten,Mike S. M. Jetten,Mark C.M. van Loosdrecht +5 more
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.

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.
Journal ArticleDOI
Free nitrous acid inhibition on nitrous oxide reduction by a denitrifying-enhanced biological phosphorus removal sludge.
TL;DR: The inhibition was found to be reversible, with the rate of recovery independent of the duration of the inhibition, but dependent on the concentration of FNAthe biomass was exposed to during the inhibition period, and a higher FNA concentration caused slower recovery.

An Updated Process Model for Carbon Oxidation, Nitrification, and Denitrification
TL;DR: Simulation results for ammonia, nitrate, soluble substrate, and biomass concentrations determined by using ASMN for three activated sludge process configurations under steady‐state and dynamic municipal‐type influent conditions are shown to be comparable with ASM#1 results.

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.

The Properties of Gases and Liquids
TL;DR: In this article, the authors estimate physical properties of pure components and Mixtures and show that the properties of these components and mixtures are similar to those of ideal gases and liquids.

Flux of Gases across the Air-Sea Interface
Peter S. Liss,P. G. Slater +1 more
TL;DR: In this paper, the use of a two-layer model to estimate the flux of various gases across the air-sea interface has been described, and the model has been used to estimate flux of different gases across different regions of the world.

AQUASIM-a tool for simulation and data analysis of aquatic systems
TL;DR: A survey over the capabilities of a new simulation and data analysis program for laboratory, technical and natural aquatic systems is given that provides methods for system identification (sensitivity analysis and automatic parameter estimation) and allows us to estimate the uncertainty of calculated results.

Nitrous Oxide from Soil Denitrification: Factors Controlling Its Biological Production
TL;DR: Increasing concentrations of nitrate, nitrite, and molecular oxygen enhanced production of nitrous oxide relative to molecular nitrogen during denitrification in soils, resulting from the sequential synthesis of nitrogenous oxide reductases.

Relative Rates of Nitric Oxide and Nitrous Oxide Production by Nitrifiers, Denitrifiers, and Nitrate Respirers
Iris C. Anderson,Joel S. Levine +1 more
TL;DR: It is predicted that aerobic soils are primary sources of NO and that N(2)O is produced only when there is sufficient soil moisture to provide the anaerobic microsites necessary for denitrification by either denitrifiers or nitrifiers.
