N2O Wastewater System We enable wastewater treatment plants to reduce total green house gas emissions from nitrous oxide (N2O). Nitrous oxide can account for as high as 90% of the total carbon footprint from wastewater treatment. Our N2O Wastewater System is the only sensor in the world to measure dissolved nitrous oxide - and real-time. The high focus on energy savings have shown to cause an increase in nitrous oxide levels. Therefore a real reduction of green house gasses needs to take N2O production and emission into account. Our sensor measures directly in wastewater and is not dependent on aereation. Using our sensor enables active control strategies for the reduction of total carbon footprit. The company is a spin-off of Unisense A/S which is the leading company with regards to microsensors.
