Instrumentation for N2O control

IWA, Instrumentation, Control, and Automation Specialist Group Nitrous Oxide Emissions

Target Audience

Process engineers and plant managers that are interested in learning more about N2O measurements and other sensors that can be used for process control mitigation.


This webinar is organised by the Instrumentation, Control and Automation Specialist Group.

Wastewater Treatment Plants (WWTPs) is an essential part of environmental management. While necessary in ensuring public health and environmental protection, these facilities have significantly contributed to nitrous oxide (N2O) emissions. In one century, N2O, has a global warming potential nearly 300 times greater than carbon dioxide, and this accentuates the urgency to address its release from WWTPs. Tackling these emissions is an environmental imperative and a step towards a sustainable future for the communities that these plants serve.

Process control is one opportunity to mitigate and minimise conditions that favour N2O formation. However, process control relies on instrumentation with accurate real-time measurements, which is a bottleneck for N2O mitigation.

This webinar will demonstrate the latest measurement technologies for N2O- measurements, including challenges that operators are facing in practice. Both off-gas, liquid phase N2O-measurements and readily available sensors for AI-driven N2O-assessment will be discussed – all from an Instrumentation Control and Automation (ICA) perspective.

Learning Objectives

Following this session, participants will be able to learn the pros and cons with different techniques for measuring N2O, and related parameters influencing N2O formation. In specific, the participants will learn:

  • What measurement techniques exist for quantifying N2O-emissions.
  • How sensor and equipment positioning, and related practical issues affect the data quality.

Which other initiatives and learning  activities exist for N2O- mitigation.
