This insightful case study features Brockton Advanced Water Reclamation Facility (AWRF), a large wastewater treatment facility located near Boston, Massachusetts, serving a population of over 132,000. Special guest John Downey, Veolia-Brockton AWRF instrumentation manager, and Adrienne Stenz, YSI process application engineer, discuss how the plant leverages online sensor technology for ammonia-based and dissolved-oxygen aeration control to achieve optimal performance and meet stringent effluent limits.
Key highlights:
- Brockton AWRF plant overview: Explore Brockton AWRF’s wastewater treatment process, which uses YSI IQ SensorNet ammonia ISE, DO, and UV-nitrate sensors to control the aeration process.
- Insights from a utility operator: John Downey shares insights on the preventive maintenance schedule implemented to ensure the reliability of 52 online sensors as control points in their system. Learn about sensor placement, routine maintenance, and measurement verification techniques for high-quality sensor data.
- Comparison of aeration control methods: The discussion covers an analysis of blower energy consumption, treatment efficiency, and effluent quality for a month between ammonia-based and dissolved-oxygen aeration trains employed at the plant.
- Operational differences between methods: Discover the operational differences between the two methods, including ease of operation, blower control schemes, and optimal sensor placement.
