  • Sedimentation Process Definition

     · September 13, 2019. Sedimentation Process Definition :- The separation of solids from a suspension during a liquid by gravity settling is termed sedimentation. The gravity force is accountable for the motion of solids through the liquid during this operation; dilute slurry is separated into a transparent liquid and slurry of upper solids content.

    10.2 Gravity sedimentation. Gravity sedimentation is a process of solid-liquid separation under the effect of gravity. A slurry feed is separated into an underflow slurry of higher solids concentration and an overflow of substantially clear liquid. A difference in density between the solids and the suspending liquid is a necessary prerequisite.
