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

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

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.

Real-world success stories

Trier Case Study

Why location and season determine the nitrous oxide balance (Dr. Matthias Stier, Variolytics GmbH)

This case study shows that the placement of the measuring hoods and seasonal recording are crucial for obtaining realistic N₂O balances. Reliable findings can only be obtained through long-term and position-accurate measurements.

Schweinfurt Case Study

Greenhouse gas emissions report for the Schweinfurt wastewater treatment plant (Dr. Matthias Stier, Variolytics GmbH)

A 12-month measurement campaign shows that stable process control permanently reduces nitrous oxide emissions and provides information on how to optimize nitrogen elimination even under good operating conditions.
