Oxygen, delivered where treatment happens.
Our nanobubble water-treatment line supersaturates water with dissolved oxygen — and, paired with Vetipont™ floating wetlands, turns tired ponds and dams into working treatment systems. Passive footprint, solar-powered edge.
Aeration that treats — not just bubbles that rise.
Conventional aeration pushes coarse bubbles that surface and burst in seconds. NBT injects nanobubbles under 200 nm that stay suspended for days, dissolve oxygen far more efficiently, and lift redox potential. That oxygen is what biological treatment runs on — so NBT Watersystems places it exactly where the biology needs it, whether in a maturation pond, a eutrophic dam, or the root zone of a Vetipont™ floating wetland.
Three ways in.
How NBT works
The nanobubble science: sub-200 nm bubbles that resist buoyancy, drive dissolved oxygen to supersaturation, and raise ORP to oxidise and disinfect.
NBT + Vetipont™
Nanobubble aeration paired with vetiver floating treatment wetlands — a biological engine finally given all the oxygen it needs.
Applications
Municipal ponds, eutrophic dams, piggery and abattoir effluent, landfill leachate, mine and process water.
Powered where it counts, passive everywhere else.
More oxygen per kWh
Nanobubbles transfer oxygen far more efficiently than coarse-bubble diffusers, so treatment is driven by a small, solar-sized power draw rather than a mechanical plant.
Retrofit, don't rebuild
The system drops into existing ponds and lagoons. No new civil works, no activated-sludge complexity, no full-time specialist operators.
Runs on the sun
PV with battery backup means no grid connection and no exposure to load-shedding — a decisive advantage for South African works.
