Wastewater Treatment Plant – Emissions of greenhouse gases

Advanced Gas Analysis for Wastewater Treatment
Nitrous oxide (N₂O), methane (CH₄), and carbon dioxide (CO₂) are key greenhouse gases generated in significant quantities during wastewater treatment. Wi.Tec offers a highly accurate, long-term stable multi-channel NDIR gas analyzer – INFRA.sens® – specifically designed for this critical application.

N₂O emissions from wastewater treatment plants show substantial daily and seasonal variations. Due to these spatial and temporal fluctuations, continuous long-term online monitoring is essential. Exhaust gas monitoring systems based on NDIR technology provide an ideal solution, offering low maintenance requirements and high temporal resolution.
Moreover, process emission monitoring enables precise quantification of oxygen transfer during biological treatment, leading to optimized processes and considerable energy savings.
