💡 Nanobubbles are resistant to degassing — they build longer-lasting oxygen reserves, improve oxidation, and control biofilms 🛒

Why Nanobubbles?

TINY BUBBLES. BIG RESULTS.

Nanobubbles are tiny, stable gas bubbles that do extraordinary things for aquaculture systems. No expensive hardware — just add a pump, gas supply, and your existing pipework.

💨

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.

🌀

Improved Mixing

Brownian motion ensures better oxygen dispersion, especially in deeper areas of your system.

⚙️

Simple Integration

Works with your existing setup — just add a pump, oxygen supply, and pipes. No complex plumbing required.

💳

Cost Effective

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

FAQ

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 NBN120S (120 m³/h) handles large commercial RAS. For help sizing, contact Biotech Aquatica with your system volume and pump details.
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), and SS316 (premium marine-grade stainless) for specialised applications. 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 2–4 weeks. Custom material options (PTFE, stainless) may take longer. Contact Biotech Aquatica for current lead times and availability.
