Sludge Storage Basins

Continuous low energy circulation of the surface maintains high dissolved oxygen layer or "odour cap" within the top 500mm of the pond 24 hours/day.

Gentle, near-laminar radial flow from the center of the pond reaches to all ends of the pond. No turbulence means no BOD is brought up to deplete the dissolved oxygen and destroy the odour cap.

Uniform surface renewal improves anaerobic digestion to reduce sludge volume, increase sludge densification.

Unlike traditional turbulent mixers, no aerosols or bacteria are released into the air.
