Nanobubbles are tiny, stable gas bubbles resistant to degassing that build longer-lasting oxygen reserves, improve oxidation capacity, and control biofilms — all through your existing pump, oxygen supply, and pipework.

Why Professionals Choose Nanobubbles

Nanobubbles are tiny, stable bubbles that do big things for your aquaculture system. Here's what sets them apart.

💨

Resistant to Degassing

Build longer-lasting oxygen reserves in water. Nanobubbles remain suspended far longer than conventional bubbles, ensuring sustained gas transfer.

🛡

Additional Biosecurity

Helps eliminate harmful bacteria, viruses, and parasites for healthier stock and cleaner water without chemical additives.

Increased Oxidation Capacity

Breaks down waste and organic materials more effectively than conventional aeration methods for cleaner system water.

Engineered for Performance

Every NBN nozzle delivers a suite of benefits that transform your water treatment capabilities.

💨 Resistant to Degassing

Build longer-lasting oxygen reserves in water. Nanobubbles remain suspended far longer than conventional bubbles.

🛡 Additional Biosecurity

Helps eliminate harmful bacteria, viruses, and parasites for healthier stock and cleaner water.

⚡ Increased Oxidation

Breaks down waste and organic materials more effectively than conventional aeration methods.

💳 Reduced O&O Use

Lower oxygen and ozone consumption is a typical outcome of nanobubble application in aquaculture.

🌱 Controls Biofilms

Reduces buildup in pipes and tanks, improving water quality and overall system efficiency.

🌀 Brownian Motion Mixing

Nanobubbles exhibit continuous random motion (Brownian motion), keeping them dispersed throughout the entire water column. In large volumes, this means more uniform oxygen distribution — even in deep tanks and far corners where conventional bubbles never reach.

⚗ Hydroxyl Radicals & ORP

Nanobubbles spontaneously produce hydroxyl radicals (•OH) when they collapse — one of nature's most powerful oxidisers. This drives a measurable increase in ORP (Oxidation-Reduction Potential), enhancing your system's ability to break down organic waste and suppress pathogens without additional chemical dosing.

💰 Cost Effective

Low upfront investment. No expensive hardware — our nozzles work with equipment you already have.

Don't Want Threads?

Standard models come with threaded fittings, but we understand not every system is the same. We can customise your connection type to suit your installation.

🔧 Solvent Fittings

Need a permanent, leak-free solvent-weld connection? We can configure your nozzle with solvent fittings for a clean, glued installation.

🔗 Unions

Want easy disconnect for maintenance? Union fittings allow quick removal and reinstallation without cutting pipes.

🔩 Flanges

For larger models or heavy-duty installs, flanged connections provide secure, bolt-together fittings — standard on NBN200+ and available on request for others.

📏 Bare Pipe

Want to handle your own fitting? We can supply with bare pipe ends so you can connect exactly how you need.

Just let us know, and we can quote you accordingly.

Supercharge Your Nanobubbles

Nanobubble nozzles work with ambient air, but the real magic happens when you feed them concentrated oxygen or ozone. Supercharge your gas transfer and unlock the full potential of nanobubble technology.

🫧

Ozone Generators

Feed ozone into your nanobubble nozzle for maximum oxidation and pathogen control. Our Redox Air and V-Series ozone generators pair perfectly with NBN nozzles. View Ozone Range →

💨

Oxygen Concentrators

Feed high-purity oxygen into your nanobubble nozzle and watch dissolved oxygen levels climb faster and hold longer than any conventional method. The Oxisat range delivers reliable concentrated oxygen on demand. View Oxisat Range →

The Combined Effect

Oxygen + Ozone + Nanobubbles = the ultimate water treatment stack. Nanobubbles dramatically increase gas transfer efficiency, meaning less gas consumed, better results, and a system that's cleaner, safer, and more energy-efficient.

Stop Overpressurising Your Oxygen Cone

Do you run an oxygen cone with a venturi? There's a much better way to dissolve gas.

🚫

The Venturi Bottleneck

You're wasting energy forcing coarse bubbles into solution. When introducing gas via a contact nozzle (venturi), you need initial pressure to overcome the downward force of the cone. But it doesn't stop there. You then need to maintain high secondary pressure inside the reactor just to force those coarse bubbles into solution.

🔬

The Solution: Shrink Your Bubbles

Shrink your bubbles. Shrink your pressure. By breaking the gas down into nanobubbles, transfer happens almost instantly. Because there is far less loose oxygen left fighting to be dissolved, you don't have to run as high of a pressure in the reactor to get the job done.

Energy Savings

By lowering the secondary pressure requirement in the oxygen cone, you significantly decrease your pump's power use. Smaller bubbles = less pressure needed = less energy consumed. It's that simple.

🫧

Superior Immediate Transfer

The surface-area-to-volume ratio of nanobubbles means dissolution happens far quicker than venturi-produced bubbles. More gas transferred, less gas wasted.

💨

Nitrogen Stripping

The tiny footprint of oxygen nanobubbles more effectively strips dissolved nitrogen gas from your water column — critical for fish health in intensive systems.

The Nanobubble Edge

You get all the inherent benefits of nanobubble technology — highly resistant to degassing, higher redox potential, and pathogen control. This isn't just a cone upgrade — it's a system transformation.

Let's Upgrade Your System

Common Questions

Q What do I need to run a nanobubble nozzle?
Just a pump, a gas supply (oxygen or ozone), and standard pipework. The nozzle is the core component — everything else you likely already have. We supply the nozzle, hose, fittings, and flow meter with every order.
Q Which model should I choose?
Match the nozzle flow rate to your system circulation rate. The NBN02 (2 m³/h) suits small systems, while the NBN300-400 (300–400 m³/h) handles large commercial RAS. For help sizing, contact Biotech Aquatica with your system volume and pump details.
Q What about pump sizing and pressure requirements?
Nanobubble nozzles have specific pressure requirements. Each NBN model has a slightly different operating pressure, and each application has different pipework, elevation, and operating pressure. That's why we size the pump for you! We can adapt to your existing pump, or size one specifically for your system — including friction loss sizing and nanobubble nozzle performance and pressure sizing. Let us do all the hard work for you.
Q Can I use these with ozone?
Yes — all NBN models are ozone compatible. For ozone applications, we recommend upgrading to PTFE fittings and ozone-compatible hose (sold separately). PVC construction is suitable for standard oxygen applications.
Q What materials are available?
Default is PVC construction for cost-effectiveness and general aquaculture use. We also offer HDPE (lightweight, corrosion-resistant), PTFE (highest chemical resistance), SS304 (durable stainless), SS316 (premium marine-grade stainless), and Titanium (ultimate corrosion resistance for the most demanding environments). Contact us for pricing on material upgrades.
Q What is the lead time for special orders?
Lead times vary by model and material. Standard PVC models are typically 1–2 weeks. Custom material options (PTFE, stainless, titanium) may take longer. Contact Biotech Aquatica for current lead times and availability.
Q What connection types are available?
Standard models come with threaded fittings. But we also offer solvent fittings, unions, flanges, and bare pipe ends. Just let us know your preference and we can quote you accordingly.
Q Can nanobubbles improve my existing oxygen cone?
Absolutely. Nanobubbles dramatically reduce the pressure required inside your oxygen cone. By shrinking bubble size, transfer happens almost instantly — meaning you can lower your reactor pressure and still get better gas transfer. This saves pump energy and improves dissolved nitrogen stripping at the same time.
