Separation process - Wikipedia
A separation process is a method that converts a mixture or solution of chemical substances into two or more distinct product mixtures. At least one product mixture of the separation is enriched in one or more of the source mixture's constituents. In some cases, a separation may fully divide the mixture into pure constituents.

Centrifugation - Wikipedia
Centrifugation is a mechanical process which involves the use of the centrifugal force to separate particles from a solution according to their size, shape, density, medium viscosity and rotor speed. The denser components of the mixture migrate away from the axis of the centrifuge, while the less dense components of the mixture migrate towards the axis.

Oil/Water Separators
the oil/water separator for wastewaters with a high suspended solids concentration. The design should be based on gravity separation of grit with a minimum detention time of 5 minutes at the maximum rate of flow. Larger basins may be used if the grit removal basin is also designed as a flow equalization basin.
Collection, Storage, and Preparation of Human Blood Cells
May 01, 2016· Density gradient separation methods (Boyum, 1968, 1977) are used when purification of cell populations is required rather than simple removal of erythroid contaminants. Density-gradient separation techniques will not yield as many cells as the simple lysis methods, but they have other distinct advantages.
Types Of Crystallization - SoliQz - Separation and Ultra,
Therefore, this staged crystallization processes is also known as a counter-current cascade. A well-known example of a process deploying the counter-current cascade principle is the TSK-CCCC process[3]. The crystal transport/separation in this process is done by cyclones, while the liquid transport is achieved by gravity.
Chapter 3 Separation Processes (Unit operations)
The equilibrium concentration represents the maximum extent a separation process can reach. The thermodynamic basis for achieving separation is that all matters in nature have the tendency to reach equilibrium. The driving force for separation of a component from the original mixture to another phase is the difference between the initial/actual
