Decantation Technique
Decantation Technique
Decantation: The process of pouring out a clear liquid from a vessel (after sedimentation), without disturbing the sediment (heavy, insoluble settled particles) is called decantation. For example; muddy water contains soil and sand in water. Soil and sand being insoluble in water, will settle down at bottom if water is allowed to stand for some time. This layer is called sediment and the deposition of sand at the bottom is called sedimentation. So, when we pour clear water into another beaker without disturbing the sediment, this is known as decantation.
Example: Mixture of Oil and Water can also be separated by the process of sedimentation and decantation. If a mixture is allowed to stand for some time, they form two separate layers. The component that forms the toplayer can be separated by decantation.
Loading: the process of increasing the rate of sedimentation is called Loading. It is done by adding some chemicals to it. Alum is used for thispurpose. Alum is soluble in water. The particles of alum entangle suspended clay particles and make them heavier. Thus, clay particles settle down rapidly.
