    J.D. Miller, in Encyclopedia of Separation Science, 2000. Introduction. The essence of particle separation by flotation is the creation of a hydrophobic surface state, i.e. a surface that is not wetted by water, a particle surface at which bubble attachment will occur leading to flotation due to the buoyancy of the particle–bubble aggregate. (Particle flotation can also, however, be

    Chi Tien, B.V. Ramarao, in Granular Filtration of Aerosols and Hydrosols (Second Edition), 2007. 1.4 GRANULAR FILTRATION VERSUS CAKE FILTRATION. Both granular filtration and filtration are used for separating particles from fluid– particle suspensions.Separation is effected through the application of filter medium but with different medium functioning.

  • Separation of Sub-micron Particles from Micron Particles

    Acoustophoresis has gained increasing attention as a gentle, non-contact, and high throughput cell and particle separation technique. It is conveniently used to isolate and enrich particles that are greater than 2 μm; however, its use in manipulating particles smaller than 2 μm is limited.
