From Microbubbles to Nanobubbles: Effect on Flotation

Attachment of particles and droplets to bubbles—the latter being various fine sizes created by different techniques (as described in detail)—forms the basis flotation, a process which indeed was originated from mineral processing. Nevertheless, chemistry often plays significant role this area, order for separation be effective, as stressed. This (brief) review particularly discusses wastewater treatment applications effect bubble size (from nano- micro-) on flotation process.
