EmiCo.
Our analyzer of greenhouse gases
The Variolytics Emission Control System (EmiCo.™) is the first analysis system in the world that can directly measure greenhouse gases produced during wastewater treatment. It enables the wastewater industry to meet their emission reduction targets by mitigating nitrous oxide (N₂O) production in the treatment process. EmiCo is a patented measurement technology coupled with process optimization software, delivering wastewater utilities a system solution to reach net-zero.

Why choose EmiCo?
Gas & Liquid Measurements
Gas & Liquid Measurements
EmiCo is the first analyzer for wastewater treatment plants that can measure values simultaneously from the liquid and gas phases. Our measuring method enables the formation of greenhouse gases in the aeration tank to be precisely monitored. In order to control the process correctly, it is important for operators to determine the formation of nitrous oxide and methane in the liquid phase. Alternatives can measure only from gas or only from liquid. EmiCo does both, and is therefore unique in the market.
Multiplexing
We can already analyze up to 8 aeration tanks simultaneously in wastewater treatment. Simultaneous measurement works by switching valves on the analyzer. The measurements are carried out serially, with each measuring point being monitored by the analyzer for 2 minutes. The multiplexing method reduces the costs for expensive measurement technology and high maintenance costs, since only 1 analyzer is required for several measurement points.

Sensitive
Sensitive
The measurements from the EmiCo. system are carried out using a process mass spectrometer. Mass spectrometry is characterized by its high measurement sensitivity. As a result, measurements can be made from the low ppb to the 100% range without any problems For monitoring emissions, gas and liquid phase sensitivities of 0.5ppm for nitrous oxide (N₂O), 0.9ppm of methane (CH₄), and 0.4ppm of CO₂ can be achieved. With EmiCo, operators of wastewater treatment plants have the possibility to monitor greenhouse gases in their aeration tanks very sensitively and in real time.
No Drift
The EmiCo system has a reference gas container next to the analyzer, which allows the system to calibrate itself automatically on a daily basis. The reference gas is a mixture of all measurement-relevant gases. This prevents a drift in the measurement result for measurements over a longer period of time. For customers, this results in savings of time and money for costly calibration of the measurement technology. The auto-calibration of the EmiCo system thus guarantees process reliability. Measured values of greenhouse gases are therefore always accurate.
No Drift
EmiCo Benefits
How do we optimize?
We initiate the optimization process through a questionnaire-based preliminary analysis. Following that, we identify preferred measuring points and calculate emission and uptake rates. By considering different scenarios, we determine the annual emissions. Our estimations cover the emission factor (EF), energy savings, CO₂e footprint, and the potential emission reduction. Additionally, we capture all emission-relevant parameters throughout the entire wastewater treatment plant and consider the impact of weather events and seasonal effects. As a result of these optimization steps, we can successfully achieve energy savings of up to 20%, emissions reduction of up to 50%, and significantly reduce the need for chemicals in the process.

How does the technology work?
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)

Patented Inlet-System
… enables simultaneous liquid and gas measurements with mass spectrometry.
In the liquid inlet there is a membrane, at the interface of which all volatile components in a liquid are constantly transferred to a vacuum through the membrane in traces. A small proportion of molecules is transferred from the gas flow in the vacuum to a high vacuum and measured in this way. he mass spectrometric measurement from the liquid and gas phase alternates continuously through a valve switch, thus enabling dual measurement from the liquid and gas phase.

EU-Goals and German Regulation
Recent data indicates that wastewater treatment plants are responsible for approx. 2% of the world’s greenhouse gas emissions -this is equivalent to the emissions of global air traffic. The EU has set itself the goal of achieving climate neutrality by 2050 (European Green Deal). In Germany, the Federal Climate Protection Act is in force. Wastewater treatment is assigned to sector 5 (waste management and other). This sector needs to reduce its emissions by at least 55% by 2030, from the current 9 milion t to 4 milion t CO₂ equivalent.
Reasons for achieving Net-Zero
Wastewater treatment plants are significant sources of greenhouse gas emissions, primarily methane and nitrous oxide. By implementing advanced technologies and efficient processes, we can substantially decrease these emissions . Moreover, emissions reduction at wastewater treatment plants is socially equitable. Water tariffs are typically structured so that everyone pays a similar rate, regardless of their income level. As a result, the burden of emission reduction is distributed fairly among the population. Unlike some climate mitigation strategies that require sacrifices or lifestyle changes, reducing emissions at wastewater treatment plants does not entail negative side effects on individual behaviour. Unlike needing to fly less or drastically alter daily habits, emissions reduction at these facilities can be achieved through technological advancements and process improvements.
