Monitoring greenhouse gas emissions from wastewater treatment

The emission of greenhouse gasses from waste water treatment processes, contributing to climate change, should be avoided. We have the know-how, experience and equipment to accurately monitor greenhouse gasses. Our expertise not only concerns the measuring methods (how to measure) but also the sampling strategies (how often and how long). We have developed a novel method for online monitoring of dissolved gas concentrations, under aerated as well as non-aerated conditions. For N2O, we showed that long-term sampling is indispensible to accurately estimate emissions and that on-line monitoring is required to identify correlations between the emissions and the parameters inducing it. An on-line gas-phase analyzer for monitoring the greenhouse gasses nitrous oxide (N2O), methane (CH4) and CO2, besides O2, is available.

The first action in preventing greenhouse gas emissions is to precisely quantify what and how much is released. Our novel online method makes precise monitoring easier and prepares the ground for improved control.
