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