Beschreibung:
<p>The aim of this work was to give a quantitative description of the gaseous nitrogen and carbon emissions of a full-scale deammonification plant (DEMON system). Deammonification accounted for the net carbon sequestration of 0.16 g CO₂/g NO₂-N. Both nitrogen dioxide (NO₂) and nitric oxide (NO) were minor trace gases (< 0.1% nitrogen output). However, in comparison, the nitrous oxide (N₂O) emission (1.3% nitrogen output) was significant. The global warming potential of the N₂O emissions from the DEMON were similar to those found in conventional simultaneous nitrification/denitrification systems; however, CO₂ emissions in the investigated system were significantly lower, thereby lessening the overall environmental effect. This was the first time such an analysis has been performed on a DEMON system.</p>
