Challenges in Upgrading One of the Last Municipal Powdered Activated Carbon/Wet Air Oxidation Plants in the U.S to Achieve Low-Level Nutrient Removal
Frederick Mueller & Paul Moran – Tighe & Bond, Rob Grasis – Town of Vernon, CT
This presentation will discuss the progress made over the last 3.5+ years (with a global pandemic and supply chain disruptions) and challenges overcome as the Vernon CT WPCF transitioned from a single-stage powdered activated carbon-based activated sludge process desired to remove color and ammonia to a 5-stage Bardenpho process with IFAS designed for low-level nutrient removal.

The Messy Economics of Septage Treatment
Austin Weidner – Tighe & Bond
This presentation explores the economics of treating septage at three POTWs throughout Massachusetts. Septage treatment can be a challenge given its variability and oftentimes utilities may overlook the hidden operating costs of treating it. However, as demonstrated in these case studies, once the actual costs of septage treatment are understood, local utilities can make more informed decisions around setting prices and improving their operations for receiving and treating septage.
