The space it occupied is filled by fluid having a weight w fl.This weight is supported by the surrounding fluid, and so the buoyant force must equal w fl, the weight of the fluid displaced by the object.It is a tribute to the genius of the Greek mathematician and inventor Archimedes (ca. 287–212 B.C.) that he stated this principle long before concepts of force were well established.

If gravity separation is used in conjunction with coagulation and flocculation, stable emulsions may be broken and separated. Oil-water separators can handle large flowrates, have low power requirements, and need minimum operator attention; however, a large residence time and therefore large equipment are required.
