Big bubbles rise and burst in seconds. Nanobubbles stay.
Nanobubble Technology
Oxygen, Delivered Where the Water Needs It Most.
A nanobubble generator dissolves air, oxygen or ozone into water as bubbles of 50 to 200 nanometres. Instead of rising and bursting at the surface, they stay suspended, raising dissolved oxygen. That supports the aerobic breakdown of organic load and suppresses algae, without chemicals.

Where It Is Used
- Lakes, ponds and temple tanks that lack oxygen
- Stretches of river with low oxygen levels
- Sewage and drains, where more oxygen helps the bacteria work (NICO VARUNA)
- Aquaculture ponds, where steady oxygen supports the fish (NICO MATSYA)
How small
Bubbles Hundreds of Times Thinner Than a Hair.
Too small to float up and burst, they stay in the water and carry oxygen all the way down.

Give a Lake Its Breath Back.

- Algae over the surface
- Fish kills in the hot months
- Odour along the shore
- Oxygen through the whole water column
- Algae held back without chemicals
- A shore people use again

Myth vs fact
What People Believe About Aeration
They treat symptoms. Oxygen lets the water recover itself.
Not if sewage keeps flowing in. Treat that first.
The science, simply
Why Tiny Bubbles Work Better.
Same water, two ways of putting air into it. Hover a number to see each part: terracotta for an ordinary diffuser, petrol for NICO.

Ordinary Diffuser
- Ordinary diffuserPushes air out as bubbles you can see, millimetres across.
- A narrow plumeBig bubbles are buoyant. They race straight up, touching little water on the way.
- Burst at the surfaceMost of the air escapes back into the sky within seconds.
- Deep water stays starvedAway from the plume, and near the bottom, oxygen stays low.
NICO Nanobubbles
- NICO nanobubble outletReleases bubbles of 50 to 200 nanometres, too small to see.
- A haze that staysNegatively charged (zeta potential up to −43 mV), the bubbles repel each other instead of merging, and hang in the water.
- The water recoversWith oxygen everywhere, bacteria break down organic load and algae lose ground. Fish return.

On site
What a NICO System Looks Like on a Lake.
Hardly anything you would notice: a small kiosk on the bank and a float on the water.

- Shore kioskHouses the pump, the NICO generator and the gas supply: air, oxygen, or ozone for heavier pollution.
- Supply lineCarries power and nanobubble-rich water out to the floats.
- Floating unitMoored where the water needs oxygen most. Land-based units are also available.
- Oxygen haloNanobubbles spread from each unit through the full depth of the lake.
- Sized to the waterMore units, or a larger model, for a larger lake.
- Life returnsClearer water, birds and fish: tracked against a baseline test, not judged by eye.

By the numbers
Small Bubbles. Measurable Results.
NICO Nanobubble India product information (niconanobubbles.com). Results depend on what flows into the water.
