In Helsinki, a large underground wastewater treatment works is using a Gasmet FTIR gas analyser for continuous emissions monitoring of pollutants such as greenhouse gases. This helps the plant in its efforts to combat climate change and also helps wastewater treatment process optimisation.

Globally, little attention is paid to gaseous emissions from wastewater treatment processes because attention is focused on the regulatory monitoring that is applied to the quality of water emissions from such facilities.

Employing a Gasmet multigas FTIR (Fourier Transform InfraRed) analyser, the plant
