• Flotation using air | EMIS

    Air is dissolved in water under pressure (57 bar). When water saturated with air is released into the floatation unit, small bells (20100 µm) are formed which interact with flocculeshaped particles.

  • Buoyancy Wikipedia

    In physics, buoyancy (/ ˈ b ɔɪ. ə n s i, ˈ b uː j ə n/) or upthrust, is an upward force exerted by a fluid that opposes the weight of an immersed object. In a column of fluid, pressure increases with depth as a result of the weight of the overlying fluid. Thus the pressure at the bottom of a column of fluid is greater than at the top of the column.
