Micro–nano bubble generators for aquaculture

Oxygen thatstays inyour pond.

Oxynity generators dissolve oxygen as sub-micron bubbles that hang in the water instead of escaping to the surface. Your shrimp and fish breathe easy at 3 a.m., eat better, and grow faster.

The 3 a.m. problem

Ponds don't fail in the afternoon. They fail before sunrise.

After dark, algae stop making oxygen and start consuming it. With paddle wheels alone, dissolved oxygen keeps sliding until dawn, the hours when shrimp crowd the edges, stop feeding, and die. Oxynity holds the line through the night.

Paddle wheel only With Oxynity Shrimp stress line, 4 mg/L

Typical pattern in a stocked shrimp pond, for illustration. Your pond's curve depends on stocking density, algae and weather.

Fewer night losses

Oxygen stays above stress levels when paddle wheels can't keep up.

Better feed conversion

Shrimp with enough oxygen keep eating, so less feed is wasted on the pond floor.

Cleaner pond bottom

Oxygen reaches the sludge layer and helps break down waste and harmful gases.

Bubble size decides everything

Big bubbles race to the surface. Nano bubbles stay.

A bubble's size controls how long it stays underwater and how much oxygen it gives up on the way. Watch three ways of putting air into the same pond.

Large · 5 mm and up

Paddle wheel

Splashes surface water. Bubbles burst in seconds and most of the oxygen goes back to the air.

Fine · 1–3 mm

Air diffuser

Better than splashing, but bubbles still rise and break at the surface within moments.

OxynityNano · under 1 micrometre

Micro–nano bubbles

Too small to float up. They drift through the whole water column and keep releasing oxygen for hours.

Inside the generator

Pond water in. Oxygen-rich water out.

Water intake

The pump draws pond water into the compact generator at operating flow.

Oxygen infusion

Oxygen from the concentrator enters at the pump suction and mixes into the water under pressure.

Nano bubble creation

Pressure and shear in the stainless steel mixer break the gas into stable sub-micron bubbles.

Back to the pond

Bubbles stay suspended through the water column and keep raising dissolved oxygen.

Results from Godavari farmers

Real ponds. Bigger harvests.

+30%shrimp yield
Low oxygen, murky water and stressed shrimp were constant problems. After installing Oxynity, the water cleared, the shrimp got healthier, and losses dropped.

Questions farmers ask

Before you buy.

Don't see yours? Call or WhatsApp us on +91 72079 47722.

What are nano bubbles?

Gas bubbles smaller than one micrometre, far too small to see. They don't float up and burst like normal bubbles, so they stay in the water and keep releasing oxygen for a long time.

Do I still need paddle wheels?

Many farmers keep a few paddle wheels for water circulation and run Oxynity for oxygen. Our team will look at your pond and stocking density and suggest the right mix.

Which model fits my pond?

As a guide: 1.5 HP for about 1 acre, 4 HP for about 2.5 acres, and 5.5 HP for about 3 acres. Heavy stocking may need more capacity.

What comes in the box?

The generator, ready to connect, with a one-year warranty. The oxygen concentrator it runs with is purchased separately; we will recommend the right capacity for your model and can supply it with your order. Delivery takes 3–4 weeks, with transport charged at actual cost from Bhimavaram.

Who services the generator?

Our own service technicians attend to farmers' service requests, working out of the Bhimavaram branch.

Is a rental option available?
