Potable water treatment: 5.4 Sedimentation

The performance of a settling tank is related to the settling velocity of the fine particles in suspension. The settling velocity is the speed at which the particles move downwards under gravity through the suspension, and for discrete particles this is dependent on the particle density and size.
