Description

BI-Zen’s agile sensor deployment and real-time data applications are enhancing the measurement and mitigation of process emissions, particularly nitrous oxide (N₂O). This submission draws on case studies from two wastewater treatment works (400,000 and 165,000 PE), showcasing the benefits of short-term monitoring campaigns. These campaigns capture N₂O alongside ammonia, nitrate, nitrite, redox, temperature, and other parameters across the activated sludge process (ASP) on a mobile platform, feeding into live dashboards and detailed follow-up analyses enriched with process and asset insights.

At the 400,000 PE site, real-time monitoring revealed intricate nitrogen pathways, providing operators with evidence to fine-tune processes and manage N₂O emissions. The data pinpointed conditions that trigger emission spikes, enabling targeted operational changes to improve compliance and sustainability. This included £/kg NH4-N treated datasets at 15-minute intervals, offering actionable insights for stakeholders.

At the 165,000 PE site, agile data capture methodologies identified process intensification opportunities. These findings will drive AMP8 effluent quality improvements, reduce energy inputs, and positively impact associated process emissions, demonstrating the dual benefits of efficiency and environmental stewardship.

This work illustrates how real-time monitoring enables proactive emission management, supports sustainable practices, reduces greenhouse gas emissions, and aligns with tightening regulatory frameworks.
