The Microbubble Generator produces microscopic gas bodies less than 10 microns in size. These have a long lifetime in aqueous solutions due to their small size. Ozone micro-and nanobubbles significantly increase the disinfection capacity and residual activity of ozone. Using this technology, the gaseous ozone half-life time can be increases from 20 min to 3 days for comparative set of similar conditions.  The PWT Microbubble generator paves the way to novel integrated and highly efficient disinfection systems.
