Description

Secondary treatment in wastewater facilities is the most energy-intensive process, readily consuming over 50% of site energy, largely due to aeration. Nitrite and nitrate, critical intermediates in biological nitrogen removal, represent an opportunity to enhance process control and optimise aeration efficiency. Leveraging real-time monitoring of these parameters can provide valuable insights into the nitrification and denitrification stages, enabling more precise aeration adjustments and uncovering pathways for operational improvements.

The Aquamonitrix automated analyser delivers continuous, in-situ nitrite and nitrate monitoring with laboratory-grade precision. By integrating this data with complementary parameters like dissolved oxygen, operators can gain a deeper understanding of process dynamics, enhancing their ability to manage the nitrogen cycle effectively. This approach has the potential to drive improvements across the “Three Es”: Energy, by enabling more targeted aeration control; Effluent, by ensuring pollutant levels meet discharge limits; and Emissions, by informing strategies to mitigate nitrous oxide, a greenhouse gas 300 times more impactful than CO₂.

This presentation will explore how real-time nitrite and nitrate data can support smarter, data-driven wastewater management, paving the way for more efficient, sustainable and cost-effective operations.
