Difference between Sedimentation and Decantation
Centrifugation and sedimentation are techniques used to separate particles based on how quickly they settle. In centrifugation, a sample is spun at high speeds, creating a force that makes particles settle at different positions according to their settling speeds. Sedimentation involves rotating a sample around different axes to create a varying force, allowing particles to settle based on their settling speeds. Centrifugation is often used in biological research to isolate and study cells and molecules, while sedimentation finds applications in areas like fat grafting and separating solids from liquids. Both methods have pros and cons, and the choice between them depends on the specific task and goals.

---|---|---|
Property |
Sedimentation |
Decantation |
Definition |
The deposition and settling of sediments. |
The separation of two immiscible substances. |
Phases involved |
Two phases: sediment in solid phase, and fluid in liquid phase. |
Either solid or liquid phase. |
Separation Method |
Uses gravitation or electromagnetism in the separation process. |
Simply pouring the two top layers of the mixture to separate substances. |
Applications |
Commonly used in water treatment plants. |
Effective for separating substances like oil and water. |
Example Usage |
Removing solid particles from water. |
Separating oil from water in a mixture. |
Sedimentation
Sedimentation is the process where particles in a liquid or gas settle down over time due to gravity. It separates substances, allowing clearer liquid or gas above the settled particles. This article discusses sedimentation, a natural process where solid particles settle in a liquid over time due to gravity. It explores applications in water treatment, geological processes, and medical diagnosis like Erythrocyte Sedimentation Rate (ESR).
In this article, we have covered the definition of sedimentation, process of sedimentation, difference between sedimentation and decantation, and other in detail.
