The process of separating of insoluble solids from liquid in its solution is done by sedimentation, decantation and filtration. These are interrelated processes.
The heavier insoluble particles are allowed to settle down at the bottom of container. It is called sediment. The pouring of liquid part without disturbing the sediment is called decantation. The process by which very fine insoluble components are removed using filter/ filter paper is called filtration.
