Aeration System Upgrade with Ammonia Based DO Control System Presentation & Tour – September 10th, Springfield


Thinking of upgrading your aeration system and/or adding nutrient sensors and analyzers? Join us for a tour on September 10th that will explore the recent aeration upgrade at the Springfield Water & SewerCommission’s (SWSC) Regional Wastewater Treatment Facility to learn how they were able to optimize treatment processes, ensuring compliance with discharge limits and minimizing environmental impact. The project centered on upgrading Springfield’s secondary treatment system to enhance nitrogen removal to ensure compliance with new NPDES permit limits. AECOM provided a detailed analysis of influent flows using data from SWSC and Veolia, that allowed for the reduction of mixed liquor return (MLR) pumps needed per aeration basin while still achieving superior nitrogen removal. This optimization combined with Hach’s system that uses both an open and closed loop controller to adjust DO concentration in real time through continuous measurement of ammonia load, led to significant cost savings. Springfield’s massive aeration basins, each 600 feet long and 100 feet wide, also underwent upgrades, including the addition of baffle walls to create distinct treatment zones, installation of mixers in anoxic zones, and replacement of aging ceramic diffusers with modern EPDM diffusers.
