Sedimentation is a method used to separate mixtures. It is based on the tendency of insoluble solid particles to settle down in an insoluble solid–liquid mixture. The mixture of an insoluble solid–liquid substance is allowed to stand without any disturbance. During this process, the insoluble solid particles settle at the bottom and the liquid floats above it. The liquid can be decanted and separated from the solid substances.

 Applications:

• To obtain clear water from muddy water
• To purify drinking water
• To separate heavy insoluble solids from solid–liquid mixtures
