Wastewater Treatment Plant – Emissions of greenhouse gases

Measuring future requirements today

Nitrous oxide (N₂O), methane (CH₄) and carbon dioxide (CO₂) are greenhouse gases that can be produced in large quantities during wastewater treatment. Wi.Tec-Sensorik GmbH has developed a highly accurate and long-term stable multi-channel NDIR gas analyser (INFRA.sens®) for this area of application.

N₂O emissions from wastewater treatment plants generally exhibit large daily and seasonal fluctuations. Due to the considerable spatial and temporal fluctuations in emissions, long-term online monitoring approaches are therefore required. Exhaust gas monitoring systems based on NDIR technology are best suited to measuring emissions due to their low maintenance costs and high temporal resolution. In addition, the monitoring of process emissions enables the quantification of oxygen transfer in the biological treatment process, which leads to process optimisation and thus significant energy savings.
