GRAVITY SETTLER - stscanadainc

2020-3-9  Gravity Settler. Gravity Settler, sometimes known as decanter, is an equipment where the entering liquid is dispersed into droplets.. The droplets are then allowed to settle by gravity in the main part of the vessel. Most settlers consist of a horizontal vessel, because the separating efficiency is proportional to the area of the phase interface.

2010-1-2  The efficiency of a cyclone chiefly depends upon the cyclone diameter. For a given pressure drop, smaller the diameter, greater is the efficiency, because centrifugal action increases with decreasing radius of rotation. Centrifugal forces employed in modern designs vary from 5 to 2500 times gravity depending on the diameter of the cyclone.
