Optimizing Wastewater Treatment: Insights from a Utility Operator

Webinar | Optimizing Wastewater Treatment - Insight from Brockton AWRF

Case Study Webinar | Optimizing Wastewater Treatment: Insights from a Utility Operator

This insightful case study features Brockton Advanced Water Reclamation Facility (AWRF), a large wastewater treatment facility located near Boston, MA, 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 preventative maintenance schedule implemented to ensure the reliability of fifty-two 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: We cover 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.
