Nanobubble case studies from India

Five pilots across sewage, turf, aquaculture and hydroponics, each with its data table and the scale of the trial. Open a case study to see the equipment, the method and what the data does not show.

How we work

Every figure on this site comes from the pilot report for that project. We state the scale, any co-treatments and what was not measured. Percentage changes are calculated from the tables. Results depend on the site, and we agree targets with you after a water assessment.

Pirana sewage treatment plant, Ahmedabad (180 MLD)

COD from 145.88 to 20.84 mg/L with oxygen; E. coli below 2 MPN/100 mL with ozone. One sample, 60-minute batches.
