Water Handbook

Gravity Separation. Most waste treatment systems employ a gravity separation step for suspended particle or oil removal. The settling rate of a particle is defined in terms of "free" versus "hindered" settling. A free settling particle's motion is not affected by that of other particles, the vessel's walls, or turbulent currents.

Gas–solid separation devices:Separation devices and Gravity settling

Gravity settling chambers. The simplest type of equipment for separating solid material from a gas stream is the gravity settling chamber in which the velocity of the gas–solid stream is reduced, and the residence time increased, so that the particles fall out of suspension under the influence of gravity. Such a device is shown in Figure 7.2.
