Filtration works by passing a mixture through a filter medium that allows only certain components to pass through while trapping others. It effectively separates solids from liquids or gases.
Common home separation methods include filtering, sieving, and centrifugation. For instance, using a sieve to separate flour from lumps or a coffee filter to separate coffee grounds from liquid are everyday examples.
Separation refers to methods used to divide or isolate components from a mixture, such as filtering sand from water or separating oil from vinegar. It is a practical process used in various situations.

Evaporation is used in everyday life for processes like drying clothes, concentrating fruit juices, and salt production. It helps remove water or other liquids, leaving behind solid residues or concentrated solutions.
Sedimentation clarifies water by allowing suspended particles to settle at the bottom of a tank due to gravity. The clearer water above the sediment can then be removed for further purification.
To separate a mixture of sand and salt, dissolve the salt in water, filter out the sand, and then evaporate the water to obtain the salt crystals. This method utilizes solubility and filtration.
