What the Houd Research Group review covers

The reviewer

Houd Research Group is a scientific consultancy service that delivers research solutions in health education, policy and clinical translation.

The review is independent of Hydro2050 and reads the published literature on nanobubble technology as a field. Hydro2050's summary of it refers to field trials in Australia, the United States and elsewhere.

What it found

Nanobubble technology effectively reduces algae and toxins, with ozone nanobubbles generating reactive oxygen species that inactivate harmful organisms without residue. Field trials in Australia, the US, and elsewhere show rapid algae collapse, improved water quality, and ecosystem benefits.

That paragraph is the review's own summary as Hydro2050 states it. The trials on the rest of this site are separate work.

Research and validation

Two reviews, and eight studies with a site behind them.

Eight of the other nine carry a measured result. The ninth is a second review, of the literature on ozone nanobubbles for algae and PFAS.
