Nanobubble case studies from India

Four pilots, with the data tables and the limits of each: the scale, what else was used and what was not measured.

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.
