OverviewExamples of applicationPreferential flotationClarification/thickeningSinking chamberTypes of gravity separators

Gravity separation is an industrial method of separating two components, either a suspension, or dry granular mixture where separating the components with gravity is sufficiently practical: i.e. the components of the mixture have different specific weight. All of the gravitational methods are common in the sense that they all use gravity as the dominant force. One type of gravity separator lifts the material by vacuum over an inclined vibrating screen covered deck. This results in the

API oil–water separator Wikipedia

The API separator is a gravity separation device designed using Stokes' law principles that define the rise velocity of oil droplets based on their density, size and water properties. The design of the separator is based on the specific gravity difference between the oil and the wastewater because that difference is much smaller than the specific gravity difference between the suspended

Gravity separation has been applied to process chrome slag by steel researchers in India. Heavy media separation (Choudhury et al., 1996) and crushing and jigging (Khan et al., 2001) are the principal techniques used. The slag is subjected to 2-stage crushing to reduce the size to −10 mm and then screened into −10 +1 mm and −1 mm fractions.

API Oil-Water Separator Definition AWC

Such separators still depend upon the specific gravity between the suspended oil and the water. However, the parallel plates enhance the degree of oil-water separation. The result is that a parallel plate separator requires significantly less space than a conventional API separator to achieve the same degree of separation.

Sedimentation is the removal of suspended solids from water by gravitational settling. Flotation is also a gravity separation, but is treated as a separate process.
