    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. To increase the size of the droplets and hence their settling rate, the dispersion

    Gravity Separation An Overview Sciencedirect Topics

    At fine particle sizes, separation by density difference under gravity, becomes less efficient. At this size range flotation is the dominant separation process, though the application of centrifugal acceleration has extended the useful separation size by gravity processes down to 5-10 m, provided the concentration criterion is favourable.
