Gravity Separation - an overview | ScienceDirect Topics

The separation by gravity is based on the difference in settling rates or terminal velocities of particles of different density and size.

Gravity separation methods fall into three broad categories: dense-medium separation, in which the particles are immersed in a bath containing a medium of intermediate density, so that some particles float and others sink; separation in vertical currents, such that advantage is taken of differing rates of settlement, as typified by jigging; and separation in streaming currents orThe Principles of Gravity Separation | Storm Water,Gravity separation is the primary mechanism of pollutant removal in stormwater treatment systems. Removal occurs downward for solids denser than water like sediment, and upward for solids lighter than water such as dispersed droplets of petroleum, oil, and paper. The former is sedimentation; the latter is flotation.GRAVITYSEPARATION: OLDTECHNIQUE/NEWMETHODS,In this article, the following gravity separation methods will be discussed:. Jigs—conventional, in line pressure and centrifugal. Pinched sluices—trays and cones. Spirals—wash water and wash waterless. Shaking tables—wet and air. Fineparticleseparators—Falcon and MGS.
