    One of the important points is the existence of backflow, which is due to the above mentioned hydrodynamic influence of the walls of the container.In the laboratory coordinate frame, the volume flux of colloidal material through a cross sectional surface area perpendicular to the sedimentation velocity is always compensated by fluid flowing in opposite direction.

    Sedimentation is the tendency for particles in suspension to settle out of the fluid in which they are entrained and come to rest against a barrier. This is due to their motion through the fluid in response to the forces acting on them: these forces can be due to gravity, centrifugal acceleration, or electromagnetism.In geology, sedimentation is often described as the opposite of erosion, i.e ...

    Chemical sedimentation is understood in terms of chemical principles and laws.
