NanoJet™ – Fresh, Clean, Oxygen-Rich Water in Any Tank

Whatever fills your tank – rainwater, municipal water or borehole water – stored water needs oxygen and movement to stay fresh. NanoJet™ gives it both. Using the pump you already have, NanoJet™ aerates, purifies and circulates every litre, with no chemicals and no moving parts.

Incoming pressure: this inline assembly is used where your incoming borehole pressure is high enough to properly aerate and mix the tank. For 5,000–10,000 L tanks that is 5–7 bar. Lower pressure? Choose the NanoJet™ Borehole Pressure Boost kit, which adds a centrifugal booster pump.

HOW IT WORKS – THREE FORCES, ONE DEVICE

1. High-velocity aeration – drives oxygen deep into the tank as nano- and micro-bubbles (under 200 nm to 50 µm), with up to 40% better oxygen transfer than standard flow.
2. Pressure-burst purification – millions of microscopic pressure bursts (hydrodynamic cavitation) break down iron and manganese compounds so they drop out of the water.
3. Complete tank mixing – intense circulation eliminates dead zones and stagnant layers, keeping sludge, slime and bacteria from taking hold.

KEY BENEFITS

1. Aeration – oxygen reaches every part of the tank, surface to floor
2. Fresh & clean water – removes iron staining, "rotten egg" smells and musty odours
3. Healthy, oxygen-rich water – stops stale, stagnant, low-oxygen conditions in your tank
4. Chemical-free – no chlorine, no dosing, no residues, nothing to store
5. Self-cleaning tank – constant circulation stops sludge and biofilm from building up
6. Protects your investment – shields geysers, pipes, appliances, drippers and membranes from staining and fouling
7. Effortless – fits inside any tank, installs in under an hour and runs automatically

FOR EVERY WATER SOURCE

1. Rainwater – keeps harvested rainwater fresh between rains; no swampy smells or sludge from roof run-off.
2. Municipal water – keeps backup-tank water fresh and ready long after its chlorine has faded.
3. Groundwater – oxygenates borehole and wellpoint water, removing iron, manganese, CO₂ and hydrogen sulphide (to below 0.1 mg/L iron).

GOOD TO KNOW

Iron and manganese removal works best at pH 7.5–8.1 (effective above pH 7.0). We recommend a water test before purchase. Use our free Water Analysis tool or book a test at capewatertech.capetown. For drinking water, stored water should meet SANS 241.
