Nanobubble technology for cleaner lakes, plants and ponds in India
Avior Aqua builds oxygen, ozone and air nanobubble generators for existing water bodies and treatment plants, with little civil work. We publish our pilot data, including its limits.
Successful pilots
Assam Department of Fisheries
95% vs 88% survival
Healthier fish and better survival in the nanobubble tanks, with steadier oxygen through the night. Operating conditions differed; the report explains how.

180 MLD STP
COD 146 → 21 mg/L
Cleaner water from raw sewage, with a much lighter organic load after one 60-minute bench batch at the Pirana plant.

Wankhede Stadium
NH₃ 1.5 → <0.5 mg/L
Better turf health, less root infection, healthier soil, less dew build-up and fewer rough patches, as reported by the ground team over the 30-day pilot.

A nanobubble is a gas bubble under 200 nanometres across. Ordinary aeration bubbles rise and burst within seconds. Nanobubbles carry a negative surface charge and stay suspended, which gives the gas far longer to dissolve.
- Under 200 nm. Thousands of times smaller than a fine-bubble diffuser bubble.
- Higher gas transfer. More surface area and longer residence time mean more gas reaches the water.
- Oxygen, ozone and air nanobubble generators. One platform, three gas feeds, chosen to suit the treatment goal.
Use cases
Lake rejuvenation
Healthier lakes and ponds: more oxygen in the water and a lighter organic load, working alongside source control.
See the lake rejuvenation use caseWastewater treatment
Better-treated water from the plant you already have, with extra aeration and no new tankage.
See the wastewater treatment use case
Aquaculture
Healthier fish and steadier oxygen through feeding peaks and warm nights, in ponds and tanks.
See the aquaculture use caseTurf and stadiums
Healthier turf with fewer rough patches, less dew build-up and better soil health, from treated irrigation water.
See the turf and stadiums use caseThree gas feeds, one platform
Compact stainless-steel units on castors, or floating frames for lakes. Specification tables for NanOxy and NanoAer are on their pages.
NanOxy
Oxygen-fed. For high dissolved-oxygen duty in lakes, aeration tanks and irrigation water.
NanOxy specifications
NanOzone
Ozone-fed. An optional add-on to NanOxy for disinfection and oxidation, sized to each site.

Frequently asked questions
Short answers. The detail is on each page.
What is nanobubble technology?
Nanobubble technology puts gas into water as bubbles smaller than 200 nanometres. They stay suspended far longer than ordinary bubbles, so more of the gas dissolves into the water. Read the full explainer.
Which water problems can a nanobubble generator help with?
Low dissolved oxygen, high organic load (BOD and COD) and suspended solids in lakes, sewage and effluent plants, fish ponds and irrigation water. Results depend on the site, so we agree targets after a water assessment.
Do I need to rebuild my plant or pond?
No major civil work is usually needed. Our units run as a side-stream beside an existing tank, pond or lake, or are plumbed into a process tank.
What have you measured so far?
We have published data from a sewage bench trial, a stadium turf pilot and two aquaculture pilots, each with its limitations. Our lake project at Rao Talao is ongoing. See the case studies.
Can I buy a nanobubble generator without a pilot?
Yes, but we recommend a pilot first, because results depend on your water. See our products.

We agree targets after a water assessment, then run a pilot before any scale-up.
