What Are Nanobubbles? Learn About PNT Nanobubbles (NBs) are gas bubbles with diameter of < 1 μm that exhibit unique physiochemical properties. Nanobubbles demonstrate unique physicochemical properties: 01 Persistent in solutions fora long period of time 02 High mass transferefficiency 03 Enhanced absorption andreactivity at the gas-liquidinterface 04 Generation of hydroxylradicals, one of the strongestoxidants, that react withpollutants and bacteria inwater Learn What's Special About PureNanoTech's Nanobubbles
