The Principles of Gravity Separation | Stormwater Solutions
Gravity separation is the primary mechanism of pollutant removal in stormwater treatment systems. Removal occurs downward for solids denser than water like sediment, and upward for solids lighter than water such as dispersed droplets of petroleum, oil, and paper. The former is sedimentation; the latter is flotation.
