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.

Customer Journey

At Variolytics, we are dedicated to providing a seamless experience for our valued clients in the wastewater industry. Our customer journey comprises nine essential steps that ensure a successful partnership. It all starts with Consultation, where we take the time to deeply understand your specific needs and challenges. Armed with this knowledge, we move forward to the 1-day Testing phase.
This hands-on experience allows you to witness firsthand the power and effectiveness of our system in measuring and reducing greenhouse gas emissions in your wastewater treatment plant. Once convinced of the benefits our system offers, we proceed to the Quotation & Agreement stage. Here, we provide you with a detailed quotation that outlines the scope, timeline, and pricing of the project. Manufacturing & Delivery is meticulously handled in our state-of-the-art facilities, guaranteeing the highest quality and precision. We take great care in ensuring secure and timely delivery to your facility, ready for the next phase. The Installation & Commissioning stage is where our skilled technicians shine. They seamlessly integrate our system into your wastewater treatment plant, ensuring optimal performance and efficiency. Knowledge transfer is vital in maximizing the benefits and ensuring the seamless adoption of the new technology. Our training equips your staff with the skills and confidence needed to operate the system effectively. Data Collection plays a crucial role in our customer journey. Our system continuously collects and analyzes real-time data, providing valuable insights into your wastewater treatment plant’s performance and emissions. With the data in hand, we move into the Optimization phase. Collaboratively, we work with you to implement targeted strategies and solutions to optimize your plant’s performance. Our commitment to your success extends beyond implementation. Our Service & Support team is always at your disposal. We provide ongoing assistance, address any concerns, and offer technical support to ensure the smooth operation of our system. Long-term partnerships are our priority, and we are here to support you every step of the way.

How does it work?

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

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

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

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)

Benefits of the Emissions Monitoring Service

Our measurements provide a precise and reliable analysis of your emissions, based on the latest scientific findings and technology. The mobile unit allows you to take measurements at different locations of your wastewater treatment plant, giving you a comprehensive picture of your emissions. The results of the measurements provide you with valuable insights that help you take targeted measures to reduce emissions and increase the efficiency of treatment process in the future. This service provides a gateway to your path to net-zero, gaining confidence in your process-state, without committing to a larger long-term project.
