Why Every Borehole System Needs NanoJet™
1. Immediate Oxidation of Raw Borehole Water
Borehole water enters storage tanks containing dissolved metals, low oxygen, gases, and anaerobic bacteria. Without early oxidation:
- Iron and manganese stay dissolved
- Anaerobic bacteria proliferate
- Gases remain trapped
- Organics stay reactive
- THMs form later during disinfection
The NanoJet System™ injects oxygen instantly, oxidizing iron, stripping gases, and preparing the water for stable treatment from the very moment it enters the tank.
2. Preventing Stagnation Through Total Tank Movement
A static tank where bulk water does not move creates:
- Stratification
- Dead spots
- Anaerobic pockets
- Biofilm growth
- Foul smells
- THM formation
The NanoJet Turbulence Enhanced Reactor (TER) induces full-body water circulation, mixing the tank from top to bottom — keeping the entire volume oxygen-rich, dynamic, and resistant to bacterial growth.
3. The Crucial Low-Cost First Step Before Filters or Ozone
Filters, UV, catalytic media, ozone, and chemical disinfectants all perform better when:
- Water is oxygenated
- Iron is pre-oxidized
- Organics are destabilized
- Sludge is lifted and not settled
- Gases have been removed
NanoJet™ reduces load on all downstream systems, lowers operating cost, extends media life, and prevents early fouling.
4. Cyclical Aeration for Consistent Water Quality
The NanoJet System™ supports timed cycles of aeration which:
- Repeatedly strip CO₂ and volatile gases
- Increase dissolved oxygen
- Boost iron oxidation
- Maintain constant turbulence
- Prevent sludge formation
- Enhance water clarity
Cyclical aeration creates predictable DO conditions, stabilizing the entire treatment process.
5. Maintaining High Dissolved Oxygen (DO) Levels
Proper DO is the most important element of a healthy tank ecosystem. High DO:
- Keeps catalytic media (BIRM®, Katalox, Greensand) active
- Prevents anaerobic bacterial coating
- Scrubs media clean
- Improves iron and manganese oxidation
- Reduces sulphides and odours
- Supports better chlorination or ozone efficiency
Water with high DO is far easier to filter, disinfect, and maintain.
6. Cleaner Tanks Through Hydrodynamic Eductor Action
The NanoJet REACTOR™ valve uses eductor design that:
- Draws water from the bottom of the tank
- Lifts and suspends settled solids
- Disrupts sludge layers
- Flushes sediment back into circulation
- Prevents dead zone fermentation
This self-cleaning hydrodynamic action keeps tanks hygienic and prevents pump fouling, line blockages, and anaerobic buildup.
7. Natural Control of Bacteria, Sulphates, and Contaminants
A NanoJet™ aerated tank suppresses:
- Iron bacteria
- Sulphate-reducing bacteria
- Anaerobic pathogens
- Slimy biofilms
- H₂S production
- THM-forming organics
Oxygen-rich water is a natural disinfectant booster and requires fewer chemicals to maintain safe water quality.
8. Eco-Friendly, Energy-Efficient, Future-Proof
Unlike air blowers, compressors, or mechanical agitators, the NanoJet System™ uses:
- Passive hydrodynamics
- Venturi entrainment
- Low-power operation
- Zero chemicals
- No moving parts
This makes it one of the cleanest, quietest, lowest-cost oxygenation and agitation technologies available.
Why NanoJet™ Excels in Borehole Water Treatment
Nano-Bubble Aeration
Ultra-fine bubbles maximize oxygen transfer for superior iron oxidation and gas stripping.
Hydrodynamic Cavitation
Shear-force turbulence generates intense localized oxidation without heat or chemicals.
Complete Tank Circulation
Eliminates dead zones, temperature layers, and chemical stratification in any tank geometry.
Self-Cleaning Operation
Continuous motion prevents sludge settlement and biofilm formation on tank surfaces.
Easy Retrofit Installation
Mounts to existing tanks without structural modification — from 1,000L domestic to 50,000L industrial.
Low Energy High Efficiency
Superior mixing and mass transfer with minimal power consumption compared to mechanical stirrers.
NanoJet™ Is the Foundation of Modern Borehole Water Treatment
Before filtration, before ozone, before UV, before chemicals — your borehole water needs to be:
Aerated • Mixed • Oxygen-rich • Pre-oxidized • Stabilized • Sludge-free
The NanoJet System™ ensures all of this happens automatically, efficiently, and affordably.
It is the smart, modern, indispensable first step for borehole water systems, drinking water storage, irrigation tanks, and industrial treatment.
