Wikipedia Meaning and Definition on 'Decantation'
Decantation is a process for the mixing mixtures. This is achieved by carefully pouring a solution from a container in order to leave the precipitate (sediments) in the bottom of the original container. Usually a small amount of solution must be left in the container, and care must be taken to prevent a small amount of precipitate from flowing with the solution out of the container. It is generally used to separate a liquid from an insoluble solid (e.g. in red wine, where the wine is decanted from the potassium bitartrate crystals). For example, to obtain a sample of clear water from muddy water, leave the muddy water in the container for some time until the mud settles and then pour out the clear water into another container.
A mixture of two immiscible liquids can also be separated by decantation. For example, the oil and water extracted from olives may be decanted to obtain the olive oil. A mixture of kerosene and water can also be separated through decantation.[See more about Decantation at Dictionary 3.0 Encyclopedia]
