What does the Emissions Monitoring Service offer?
Our emission monitoring service is tailored to wastewater treatment plants and, in addition to consulting, also includes a 1-day test measurement. Variolytics mission is to empower wastewater treatment plants to achieve sustainability goals by providing innovative solutions. With our test measurement, we help our customers understand their current emission levels and identify areas for improvement. We also offer support to the treatment plants that want to achieve net-zero emissions, helping them to develop and implement strategies to reduce their carbon footprint and meet their sustainability goals. This service is designed as a gateway to showcase the potential of a permanent EmiCo solution. At the end of the evaluation, customers will receive an impact study, determining the current emission rates of the treatment plant and savings potential.

How does it work?
How does it work?
Mobile Analysis Unit
Mobile Analysis Unit
Our measurements are provided through a mobile analysis unit (mass-spectrometer) housed in a specially equipped vehicle. The vehicle is positioned near the aeration basins. From the measuring spot at the basin, a probe line delivers the sample to the analyser in the vehicle. This set-up enables flexible real-time measurements of emissions at wastewater treatment plants.
Hood and Sample Line
Hood and Sample Line
A hood is connected to the EmiCo system via a 100-metre sample line. The hood is positioned on the surface of the aeration basin and captures the exhaust air. Our in-situ probe is placed under the hood and provides liquid phase measurements. By changing the position of the hood at different points in the biological step, customers receive a broad overview of their emissions.
Emission Rates
Emission Rates
In addition to analysing the concentrations of N₂O and CH₄ from the liquid and gas phase, temperature and flow of the exhaust gas is measured, as well as O₂ and CO₂. This provides precise insights into the formation, elimination and emission rates and gives customers additional information that can help optimise their plant.
Emissions Report
Emissions Report
After the test measurements are completed, customers will receive a detailed emissions report, as well as a comprehensive method statement of the analysis. This report contains important information such as the CO₂ footprint and the emission factor of the wastewater treatment plant. This data will help customers take targeted measures to reduce emissions and reach net-zero.

What can be measured?
Mass-spectrometry-based analysis has a large measuring range, with low detection limits from the ppb to the 100% range. EmiCo provides multi-parameter measurements in real-time from the liquid & gas phase. EmiCo is calibrated to measure the following parameters, in relevant concentrations for emission control in wastewater:
- Nitrous oxide (N₂O)
- Methane (CH₄)
- Oxygen (O₂)
- Carbon dioxide (CO₂)
- Nitrogen (N₂)
