Nanobubble technology oxygenates water at greatly reduced cost

News Snapshot:

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...
