Sedimentation and Decantation

Sedimentation involves allowing insoluble solids, known as sediments, to settle at the bottom of a liquid container.
Decantation is the process of slowly transferring liquid from a container without disturbing settled sediments.
Example of decantation: pouring water from a sand-water mixture, leaving the sand behind.
Common practical applications of decantation include washing rice, where water is poured out while retaining rice grains.
Separating immiscible liquids, such as oil and water, can be accomplished via decantation since oil floats on water.
Laboratory separation funnels can aid in efficiently separating immiscible liquids.

Filtration

Filtration is a method used to separate components of suspension mixtures using a filter.
A filter consists of a porous mesh of fibers, allowing liquids (like water) to pass through while trapping impurities and solids.
The liquid that successfully passes through the filter is known as filtrate, while the trapped solids are referred to as residue.
Filtration is commonly utilized to remove unwanted particles from liquids, such as purifying water for personal or business purposes.
Typical contaminants trapped during filtration include dirt and sand, which do not pass through the filter.
