Seasonal and diurnal variability of N 2 O emissions from a full-scale municipal wastewater treatment plant

A Novel Comprehensive Procedure for Estimating Greenhouse Gas Emissions from Water Resource Recovery Facilities

“…Measurements should be done every 10-20 min by monitoring GHG concentration in the off-gas for a minimum of 24 h up to one week. In the case of multiple day monitoring, it is preferable to also include weekend samples, which significantly contribute to increase the GHG emissions estimation accuracy (Daelman et al 2015).…”

“…N 2 O is currently the single most important ozone-depleting gas (Ravishankara 2009). N 2 O emissions occurring in aerated zones are lined to nitrogen load, volumetric stripping, and the role of ammonia-oxidizing bacteria (Daelman et al 2015;Guo et al 2013). Stenström et al (2014) have found that N 2 O formed in liquid phase during denitrification accumulates mainly in the water volume until aeration starts and thereafter it is quickly stripped off to the atmosphere.…”

Nitrous oxide emissions in a membrane bioreactor treating saline wastewater contaminated by hydrocarbons

“…This can be of huge importance and requires further exploration. Indeed, there is an imperative need of long terms analysis in order to take into account the evolution of the biomass properties over the time and their influence in N 2 O formation (Daelman et al, 2015;Sperandio et al, 2016).…”

Greenhouse gases from wastewater treatment — A review of modelling tools

“…In recent years, new GHG quantification and measuring techniques have increased the available data and literature on GHG emissions (GWRC, 2011;Daelman et al, 2012;Daelman et al, 2015). The Intergovernmental Panel on Climate Change (IPCC) has established emission factors to provide quantification guidelines for estimated GHG emissions in WWTPs.…”
