From colloidal dispersions to colloidal pastesthrough solid–liquid separation processes [PDF]

open access: yes, 2005
Solid–liquid separation is an operation that starts with a dispersion of solid particles in a liquid and removes some of the liquid from the particles, producing a concentrated solid paste and a clean liquid phase.
