Based on 2-years data from Danish WWTPs, you get an insight into the reduction potential in ton CO2 equivalent.
Monitor the N2O concentration in the liquid and use N2O as a control parameter for carbon dosage in the denitrification process.
Significant 3-fold increase in IPCC2019 wastewater N2O emission factor supported by Danish studies.
Information regarding N2O emissions from trickling filters is limited, partly caused by the difficulties in capturing off-gases.
The available data show that the nitrous oxide emission varies in time and between wastewater treatment plants.
VCS Denmark, one of the largest and oldest water and wastewater companies in Denmark, is actively committed to resource optimization
Frederikshavn Water Utility contacted Unisense Environment for assistance in determining the actual N2O derived CO2 footprint
WWTP Pforzheim uses an N2O sensor to determine the formation rate of nitrous oxide in the denitrification and the nitrification zone
