What is Decanting › Definition and Meaning
Process separating a solid from a thick liquid
Decanting is a process that deals with the separation of a dense solid or liquid other fluid that is characterized by less dense and then by this feature will occupy the top of the mixture forming both. It is widely used to separate mixtures of heterogeneous type which are formed by a substance solid and a liquid or two dense liquids.Although often the terms are used interchangeably, we note that the decantation is not matched by sedimentation, because actually the latter is acting gravity separating the solids from the liquid.
It used to instances of water purification How is the process?
This procedure is recurrent in the processes of purification of water to thus extract the heavier particles before proceeding to the filtration. It allowed to stand and observed a certain time the solid particles suspended in the liquid will be deposited at the bottom of the container.Once the action mentioned just holds the liquid be transferred to another container and leave the basis of the solid material and can be removed very simply.
Decanting is not viable in mixtures homogeneous type such as water and alcohol, while it is possible in such heterogeneous mixtures is the case of water and oil.
To carry out the process of decanting a separator in which the mixture is placed in question is used. Water is descending to the base oil while its intrinsic characteristics remain on the container surface. When the key of the ampoule is opened the liquid will transfer to a container placed under the blister. Then the key is closed so that the decantation is achieved a success.
colloquial use
As usual result is that the concept is used in the lenguajecoloquial with a symbolic meaning, to refer to those separations that occur for not belonging to integrate everything, being the separation factor different attitudes or opinions they express or represent.Photo: iStock - Maxiphoto

The most common is generated by entrainment of water from the solid material
One of the most common sedimentations happens with the solid material is mobilized by a stream and deposited by it in the bottom of the river in an artificial canal in a reservoir or in a space that was specially built for the sediment accumulates there.Water currents and involving high flow velocity entrainment are capable of carrying sediments, are therefore the areas characterized by depressions in which usually occur sedimentation. These depressions in which accumulated sediments appear is popularly known as sedimentary basins. The law of gravity is largely responsible for settling. On the contrary, the raised areas are affected by the erosion process.
Procedure involved in water purification and sewage treatment
We note that sedimentation is a need to process instances of the purification of water and wastewater treatment. Recall that clean drinking water is a fundamental and very important process so that the water is optimized for consumption human and does not involve any risk to health and the treatment of wastewater is a process that involves several actions to to eliminate or reduce to a minimum the pollution of water.There are some devices that assist in the production of sedimentation in the aforementioned cases such as: sand trap, decanters and filter prey. All retention pursue those large solid parts.
