How Optimized Aeration Systems Can Save Millions at Treatment Plants


Part 1: AFT Arrow

By Matt Steiner & Jen Murphy

Many utility ratepayers are currently struggling with economic security. At the same time, energy costs are rising and the impact of uncertain material and equipment markets is driving project costs up and making capital planning less predictable. As such, it is important that as engineers that we leverage all available tools to optimize each project’s capital and operational costs. Almost just as important is sharing what we learn with not only our colleagues, but the wider engineering community.

The Aeration systems at Resource Recovery Facilities (Wastewater Treatment Plants) account for 30 to 80 percent of a plant’s energy usage, making them typically the single largest source of energy use within the facility. They’re also the most complex and capital intensive systems within a plant. This integral system, which ... (more)
