Heat Hiding in the Treatment Plant
Municipal and industrial wastewater plants vent warm, humid air from buildings, digesters, sludge drying and aeration exhaust — heat that can be captured for space heating, inlet air preheat or sludge dewatering.
Recovery Points
- Building & odorous-air exhaust: recover ventilation heat to warm incoming make-up air in cold climates.
- Sludge drying off-gas: closed-loop cores return latent heat to the dryer.
- Digestate & process streams: preheat feed or building heat with isolated air-to-air recovery.
Why Air-to-Air
Wastewater air is corrosive and often carries H2S. Epoxy-coated or polymer cores isolate the streams and resist the environment, with no liquid cross-contamination.
