In the most fundamental term, a grease trap or grease inceptor functions by cooling warm or hot greasy water. By allowing the fat, grease and oil (FOG) to cool, a grease trap is able to separate the different layers of wastes with water. FOG are lighter in density and float at the surface of the tanks, and the cooled water – minus the FOG ...
While most engineers in industries that process dry materials know what a gravity separator (Figure 2) does, its work is difficult to define with precision. The statement "a separator classifies dry, free-flowing, granular mixtures by weight or bulk density or specific gravity" is accurate. But a more precise definition would add the ...
Operation Mechanism. The working mechanism of a cyclone separator can be summarized in the following steps: The particle-laden airstream enters the cyclone separator at the inlet. This air is guided to move in a spiral motion. Due to the shape of the cyclone and the swirling motion imposed by the cyclone's design, a "vortex" is created.

The gravity separator, also known as fluidized-bed separator, air table, or density separator, makes a highly sensitive dry separation on the basis of one of three particle characteristics – density, size or shape. When two of these characteristics are controlled within certain limits, the gravity separator is unmatched in its ability to ...
The separation principle of high-speed centrifuge depends on the difference in the specific gravity of two different liquids.

Spiral concentrators are gravity-based separation devices used for the concentration of coal, heavy minerals, and ores with a relatively high specific gravity. They work on the principle of the spiral motion of slurry within a specially designed trough, creating a centrifugal force that aids in the separation process.
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.
A fat separator is a device used to separate fats from liquids. It works by passing the liquid through a filter paper which has tiny holes in it. The liquid passes through the holes but the fats stick to them. After this process, the liquid will appear clear and the fats will remain at the bottom of the container.
In a cyclonic separator, typically air laden with dirt and dust is pumped through the top of a vertical cylinder with a conical bottom. The fast-moving air enters the chamber at the top of the cylinder and begins rotating violently. As that happens, a mini tornado or cyclone forms [source: Wacharawichanant].
In a horizontal three-phase separator, fluid or liquid enters the vessel through an inlet and promptly hits an inlet diverter. The sudden impact and change of direction assist in releasing the gas by breaking the surface tension of the fluid. In the liquid collection section of the vessel, the oil separates and frames a layer above the water.
A gravity concentrator namely "vibrating table" has been developed with the objective of increasing the product quality of density based physical separation processes. The system is mainly composed of a vibration unit, an inclined chute, TW and WW jets. The principle idea of the separation is to combine the involved forces of a …
Oil water separators are designed specifically to target oil based on the gravity difference between oil and water, allowing for heavier solids (sludge) to settle to the bottom while oil rises to the top, leaving additional wastewater in the middle layer. Sludge can then be scraped away, oil can be skimmed off the top, and wastewater can move ...
The gravity separator is a specialized piece of machinery designed to separate particles of similar size that differ in specific density.

The Knelson Concentrator is a compact hatch centrifugal separator with an active fluidized bed to capture heavy minerals. A centrifugal force up to 60 times that of gravity acts on the particles, trapping denser particles in a series of rings (riffles) located in the machine, while the low-density particles are flushed out.
The Centrifuge, one of the most important auxiliary equipment on the ship, works on the basic principle of separation based on the difference in the specific gravity of two different liquids. Gravity separation is the traditional method which is used, but it takes a while as gravity is the sole thing responsible for settling out.
The application of heat will speed up the separation process. Separation occurs due to the differences in specific gravities (density) of the liquids and solids. Heavier denser materials settle at the bottom, lighter less dense materials at the top. As mentioned, gravity is responsible for the separating and this takes quite a while.

1. Introduction. In its simplest definition, gravity concentration is a class of methods which take advantage of the density differences among mineral particles [1], [2], [3].As a result, particles of which densities are different from each other have their own relative movement against the forces of the gravity depending on the factors such as …
To calculate the size of an empty vessel gravity separator, it is first necessary to calculate by the use of Stokes' Law the rise velocity of the oil droplets. The size of the separator is then calculated by considering the path of a droplet entering at the bottom of one end of the separator and exiting from the other end of the separator.
All gravity separators have the following features: Gas/liquid separation section with an inlet diverter to remove the bulk of the liquid from the gas. In most designs, the inlet diverter contains a downcomer that directs the liquid flow below the oil/water interface; Gravity-settling section, this section allows a retention time so that proper ...
The simplest separator is the gravity separator. The rule of thumb used to size a gravity separator is that the superficial velocity of vapor at the free surface should be less than 0.3 m/s. When the velocity is greater than this, the carryover increases rapidly. Kataoka, et al. (1981) describe the carryover process in some detail.
Gravity, coalescence, and filtration. Oil separators use three main methods to accomplish their mission: gravity, coalescence, and filtration. Gravity helps the oil rise to the surface, forming a separate layer. Coalescence encourages tiny droplets of oil to come together, making removing them easier. Filtration, a precise process, captures any ...
