Making emissions visible –
for climate-neutral wastewater treatment plants.

Measure, analyze and optimize emissions – all from a single source

Play

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

Why emission measurement is crucial now

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.

    • Frequently asked questions

    Variolytics enables the real-time measurement of nitrous oxide, making critical processes visible. Based on this data, aeration and nitrogen management can be specifically optimized, significantly reducing emissions and energy consumption. The solutions are easily integrated, meet regulatory requirements, and contribute measurably to climate neutrality.

    The Variolytics one-package solution combines measurement technology, software, and analysis in one system, delivering precise emissions data in real time. Thanks to simple installation, cloud connectivity, and minimal maintenance, the solution is ready for immediate use and reliable in operation. Operators benefit from measurable emission reduction, energy savings, and a solid basis for regulatory reporting.

    Nitrous oxide is approximately 265 times more harmful to the climate than CO₂. Even small quantities can significantly increase a plant's CO₂ footprint.
