N2O Wastewater System
If your goal is to reduce the environmental impact from N2O emission, you need robust and reliable real-time N2O measurements in order to implement active control strategies. Read more...
Robust and reliable real-time N2O measurements
With the N2O Wastewater System, you get a valuable tool to understand the biological processes that lead to N2O formation and emission. Once installed, the N2O Wastewater Sensor will provide you with real-time data around the clock. This makes it possible for you to directly monitor and control the N2O emission from your wastewater treatment plant.
Lowering aeration to a minimum has been a popular strategy at many wastewater treatment plants to achieve energy savings and cost reduction. However, research shows that this leads to increased production and emission of nitrous oxide. When you apply the data from the N2O Wastewater System to balance between aeration savings and N2O production, you can achieve energy savings and a documented positive environmental impact.
You place the N2O Wastewater Sensor directly in the activated sludge where it measures the production of nitrous oxide during both nitrification and de-nitrification processes. You can either hang the sensor’s waterproof casing directly in the water to let it move freely with the current flow or you can choose a fixed position. With its built-in temperature sensor, the N2O Wastewater Sensor delivers post-normalized data.
The signal from the N2O Wastewater Sensor is transmitted via a 4-20 mA signal from the N2O Wastewater Controller to a SCADA or PLC system. You can also log directly on the N2O Wastewater Controller for later downloading on a USB-stick.
