Mechanisms of N2O production in biological wastewater treatment under nitrifying and denitrifying conditions.
TL;DR: N2O production via hydroxylamine oxidation is favored at high ammonia and low nitrite concentrations, and in combination with a high metabolic activity of ammonia-oxidizing bacteria (at 2 to 3 mgO2/l); the contribution of nitrifier denitrification by AOB increased at higher nitrite and lower ammonia concentrations towards the end of the experiment.
Journal ArticleDOI
Oxidation Kinetics of Fe(II) in a Eutrophic Swiss Lake
TL;DR: In this paper, the rate of oxidation of ferrous iron was measured in samples from Lake Greifen, a eutrophic lake in Switzerland, using an automated flow injection analysis system employing luminol-based chemiluminescence detection of Fe(II).
Journal ArticleDOI
Light-induced redox cycling of iron in circumneutral lakes
TL;DR: The light-induced redox cycling of Fe II /Fe III was studied both in laboratory experiments and in the field in two circumneutral Swiss lakes: Greifensee, a eutrophic, natural water body, and Melchsee, an oligotrophic, artificial mountain lake.
Journal ArticleDOI
Isotope Signatures of N2O in a Mixed Microbial Population System: Constraints on N2O Producing Pathways in Wastewater Treatment
Pascal Wunderlin,Moritz F. Lehmann,Hansruedi Siegrist,Béla Tuzson,Adriano Joss,Lukas Emmenegger,Joachim Mohn +6 more
TL;DR: Measurements of site preference (SP) and bulk (15)N/(14)N ratios of nitrous oxide (N(2)O) by quantum cascade laser absorption spectroscopy (QCLAS) are presented as a powerful tool to investigate N( 2)O production pathways in biological wastewater treatment.
Journal ArticleDOI
Determination of biogenic and fossil CO2 emitted by waste incineration based on 14CO2 and mass balances
Joachim Mohn,Sönke Szidat,Johann Fellner,Helmut Rechberger,R Quartier,Brigitte Buchmann,Lukas Emmenegger +6 more
TL;DR: A field application of the radiocarbon ((14)C) method was developed to determine the ratio of biogenic vs. fossil CO(2) emissions from waste-to-energy plants (WTE).
