NanoJet™ Technology — No chemicals. No confusion.

Your borehole water,
clean and clear.
Permanently.

The NanoJet™ system removes odours and speeds up the removal of iron, manganese and bacteria, using nothing but oxygen, movement and physics. Trusted for water treatment across Cape Town and South Africa. Fits inside any water tank. Works automatically. Maintenance is minimal.

*Full iron removal needs a pH of about 7.2–7.5 or higher (NanoJet™ lifts pH around 1 point by stripping CO₂) and enough oxidation time: air is slower; with ozone, about 10 minutes. Test your water first.

How NanoJet™ works

Three forces. One device. Clean water.

Your pump does the work. Physics does the rest: oxygen-rich, fast-moving water that speeds up oxidation and gets more out of every filter and every dose of ozone or treatment chemical.
1

High-velocity aeration

Your pump recirculates water through the NanoJet™ system, injecting oxygen deep into the tank.

2

Oxidation force multiplier

As the jet leaves the nozzle, intense shear and collapsing micro-bubbles create a high-energy zone that speeds up oxidation, helps ozone and dosed chemicals react faster, and puts bacteria passing through it under stress. (Engineers call this hydrodynamic cavitation.)

3

Complete tank mixing

Intense turbulence moves and circulates aerated water eliminating dead zones, sludge, and bacterial growth.

Fresh water in every tank!Animation: a NanoJet™ firing a jet of air-rich water across a tank. This is the aeration and mixing that starts iron and manganese oxidising.

🔄 Complete the system

Keep the tank maintenance-free

Install the NanoJet™ STANDARD Iron & Sludge Removal Kit, plumbed on a timed loop into the tank. It continuously polishes the water — filtering suspended sludge down to 1 micron and returning it clean — so the sediment the NanoJet™ lifts off the tank floor gets removed instead of resettling. No more manual tank cleaning.

Borehole flow fluctuating or dropping off? That's a common problem, not a fault in the NanoJet™ — but a Standard Kit run off an unstable pump will lose turbulence and cavitation strength when yield dips. The Premium Kit's own booster pump keeps pressure constant regardless of what the borehole is doing.

Check your pH first
Iron won’t oxidise and drop out of water below a pH of about 7.2–7.5. NanoJet™ strips out CO₂, which lifts pH by around 1 point, so mildly acidic water often gets there on its own; more acidic water needs pH correction first.
