The Effect of Particle Sedimentation on Gravity Filtration ...
Simulation of cake formation of mono-sized and dual-sized particles under gravitational sedimentation and filtration is presented. The dynamic analysis proposed by Lu and Hwang in 1993 is applied to examine the local cake properties formed under a falling head by considering the hindered settling effect of particles in the slurry and the variation of the pressure drop across the filter septum.
Filtration Equipment Information | Engineering360
Gravity sedimentation - Gravity sedimentation is used to reduce the solids concentration of the material to be processed. It can be either a clarification or a thickening process. ... Gravity filtration equipment uses the hydrostatic pressure of a pre-filter column above the filter surface to generate the flow of the filtrate. Common products ...
Filtration Theory - NPTEL
There are four basic filtration mechanisms: SEDIMENTATION: The mechanism of sedimentation is due to force of gravity and the associate settling velocity of the particle, which causes it to cross the streamlines and reach the collector. INTERCEPTION: Interception of particles is common for large particles. If a large enough particle follows the ...
