Nanobubble applications and use cases
Where nanobubble generators fit in water treatment, where we have run pilots, and the strongest measured result from each.
Choose a use case
Lake rejuvenation
Healthier lakes and ponds: more oxygen in the water and a lighter organic load, working alongside source control.
See the lake use case
Wastewater treatment
Better-treated water from the plant you already have, with extra aeration and no new tankage.
See the wastewater use case
Aquaculture
Healthier fish and steadier oxygen through feeding peaks and warm nights, in ponds and tanks.
See the aquaculture use case
Hydroponics
Stronger starts and faster seedlings: higher germination across crops and steadier growth through the summer heat.
See the hydroponics use case
Turf and stadiums
Healthier turf with fewer rough patches, less dew build-up and better soil health, from treated irrigation water.

Lake rejuvenation
The problem. Lakes and ponds that receive sewage and run-off lose dissolved oxygen, grow algae and build up sludge.
What nanobubbles do. They raise dissolved oxygen through the water column and support the bacteria that break down organic matter. They work alongside source control, not instead of it.
What we have measured. Our lake project at Rao Talao in Mira Bhayandar is ongoing, so we have no published lake results yet. See the lake use case.
Wastewater treatment
The problem. Aeration tanks at sewage and effluent plants that cannot hold dissolved oxygen, or that need more polishing before discharge.
What nanobubbles do. They add oxygen and oxidation from a side-stream unit beside the existing tanks, with no new tankage.
What we have measured. In a bench trial on raw sewage from the 180 MLD Pirana STP, oxygen nanobubbles brought COD from 145.88 to 20.84 mg/L and BOD from 72 to 8 mg/L in 60 minutes. This was one sample at bench scale. Read the Pirana case study.
Aquaculture
The problem. Dissolved oxygen falls at night and after feeding, and ammonia builds up as stocking rises.
What nanobubbles do. They keep oxygen steadier through those peaks, from a unit beside the pond or tank on a recirculation loop. For intensive systems, see oxygenation for biofloc and RAS fish farms.
What we have measured. In the Tengra tank trial at Hajo, Assam, day-100 morning dissolved oxygen was 8.2 and 7.8 mg/L in the nanobubble tanks against 6.0 mg/L in the control. Operating conditions differed between the tanks. Read the Tengra case study.
Hydroponics
The problem. Germination and early seedling growth depend on oxygen at the root zone, and warm water holds less of it.
What nanobubbles do. They deliver oxygen-rich water to germination trays and nutrient solution.
What we have measured. At Rucon Hydroponics, germination averaged 80.25% on nanobubble water against 69.75% on regular water across four crops. Read the Rucon case study.
Turf and stadiums
The problem. Hard, high-TDS or ammonia-laden irrigation water can stress sports turf.
What nanobubbles do. They treat the irrigation water before it reaches the pitch.
What we have measured. At Wankhede Stadium, over a 33-day pilot, irrigation water TDS fell from 750 to 550 mg/L and ammonia from 1.5 to below 0.5 mg/L. Read the Wankhede case study.
How a project runs
Every application starts the same way. We assess the water and the site, agree what to measure, run a pilot on part of the system, and only then size a full installation. Results depend on the site, so we agree targets after the water assessment.
Not sure where you fit?
Most enquiries start with a symptom: a lake that smells in summer, an aeration tank that cannot keep dissolved oxygen up, a pond that crashes at night, or turf water that is too hard. Describe it to an engineer and we will tell you whether a pilot is worth running. We will say so if it is not.
Tell us about your water body or plant
We agree targets after a water assessment, then run a pilot before any scale-up.
