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.
For a simple gravity separation tank, where a residence time is allowed for an acceptable level of separation between base salts and water (BS&W) and a heavy oil like that found in the oil sands of Alberta, Canada or similar scenarios. A case in point requires separation between 2% BS&W and 18% bitumen + 18% diluents (dilbit).
The new separation mechanism, achieved through the use of appropriate, closely spaced, inclined channels leads to significant suppression of the effects of particle size in the particle size range −2 + 0.075 mm, even at low solids concentration. For example, over the size range 0.25 to 2.0 mm Ep values of 0.06 to 0.08 were obtained. Keywords:

The gas gravity separation section then provides preconditioning of the gas—and its entrained liquid load—ahead of the mist extractor. Two approaches to sizing this part of the separator to remove liquid droplets from the gas are the Ks method (Souders-Brown equation as shown in Eq. 1) and the droplet settling theory.

Basic Principle of Gravity Separation. The essence of gravity separation is the three basic processes of loosening, layering and separation. 1. Loosening. The materials in the separating process are pushed and dispersed in the moving medium due to the action of gravity, fluid power and other mechanical forces. 2. Layering

For placer gold, the lower limit particle size can reach 0.04mm on the premise that the specific gravity difference is ≥ 1.25 and the ore monomer is separated. The process is simple and the equipment processing capacity is large, so the application effect in coarse-grained gold separation is very good. 2. Gold selection by Shaking table

Organic solids are lighter than inorganic solids. Some are lighter than water, although most have specific gravities between 1.1 and 1.5. The specific gravity of most inorganic solids ranges from 1.5 to 2.65, with sand 2.45 to 2.65. Some clays have a much lower specific gravity because of entrained water, on the order of 1.5.
