Measure emissions precisely. Reduce costs. Achieve climate goals.
From initial measurement to optimization – we support wastewater treatment plants on their path to climate neutrality with precise measurement technology, intelligent software, and AI.
Our mission is to guide wastewater treatment plants towards climate neutrality through the intelligent integration of precise measurement technology, software, and AI-driven process optimization.
We make emissions in the biological treatment stage visible, identify direct greenhouse gases such as nitrous oxide and methane, and enable targeted measures to improve treatment performance and reduce emissions through data-based analysis. With innovative solutions and user-oriented consulting, we are setting new standards in wastewater treatment – for a sustainable and climate-friendly future.
Measure, analyze and optimize emissions – all from a single source
Nitrous oxide (N₂O) is over 260 times more harmful to the climate than CO₂. The new EU Wastewater Directive will require operators to monitor and reduce direct emissions. Variolytics offers a one-package solution that combines measurement, analysis, and optimization – simple, precise, low-maintenance, and cost-efficient.

Real-world success stories
Why Unstable Nitrification Can Drive Nitrous Oxide Emissions
This case study demonstrates how nitrite accumulation can be linked to increased nitrous oxide emissions and may indicate unstable process conditions. Through continuous measurements and correlation with operational data, potential causes can be identified and specific strategies for stabilizing nitrification can be developed.
Why Incomplete Denitrification Can Cause High Nitrous Oxide Emissions
This case study demonstrates how incomplete denitrification can lead to increased nitrous oxide emissions. Continuous measurements made it possible to identify the emission patterns and derive targeted adjustments to the process control system, resulting in an estimated reduction in N₂O emissions of approximately 75%.
Why Exhaust Gas Data Reveals New Opportunities for Ventilation Optimization
This case study demonstrates how continuous off-gas measurements can reveal excess aeration that cannot be detected using conventional DO sensors alone. By analyzing CO₂ and O₂ together, it was possible to identify a potential reduction of up to 7% in blower energy consumption without compromising treatment performance.
Why Low N₂O Emissions Are Not Yet the End of Optimization
This case study demonstrates how continuous off-gas measurements can reveal further potential even when N₂O emissions are low. The analysis identified excess aeration and showed the potential to reduce aeration energy by up to 16% without compromising process stability.
