Simple Wastewater Solutions for Small Municipalities | WEFTEC SERIES | EP 12
Dave Gibson of BioWorks explains extended aeration, cold weather design and lagoon upgrades for small town wastewater, and how costs compare with MBRs.
Small towns need wastewater treatment that works without a lot of complexity. In this Engineers for Communities episode, Dave Gibson from BioWorks walks through the wastewater systems his company builds for small municipalities. He covers aeration, design for cold climates, and how the costs and day-to-day operation compare with traditional methods and membrane bioreactor (MBR) systems.
Guest
Dave Gibson, BioWorks.
In this episode
- Simpler treatment: Gibson describes the move from traditional methods to BioWorks' extended aeration systems, built for the needs of small municipalities.
- Aeration: how BioWorks uses fine bubble diffusers and moving aeration systems to raise efficiency, cut energy costs and make maintenance easier.
- Cold climates: how the designs keep systems from freezing through every season without costly heated enclosures.
- Moving off a lagoon: why Gibson says operators moving from a lagoon to an activated sludge system find these systems easier to run.
- Cost and nitrogen limits: Gibson compares cost and operating complexity with MBRs, explains how the designs can meet strict denitrification requirements, and shares examples of lagoon upgrades.
