Nanobubble technology oxygenates water at greatly reduced cost

Nanobubbles may be tiny, but they have big potential when used successfully in sectors such as irrigated agriculture, aquaculture and water treatment. What's hampering their wide-scale adoption, however, is cost. They are expensive to generate. That's a problem NanobOx founders, Dr Mohammad Reza Ghaani and Dr John Favier, say their novel, nanobubble-based technology for low-cost water aeration has solved. Bubbles play a significant role in maintaining levels of dissolved oxygen in process waters — think fish tanks — and nanobubbles are particularly attractive because they have an oxygen transfer efficiency rate of about 85 per cent. This compares with just…
