Filtration is a process of separating solid particles from a liquid by passing the mixture through a filter. The filter pores are small enough to trap the solid particles, while allowing the liquid to pass through. The solid particles that are retained on the filter are called the residue, while the liquid that passes through is called the filtrate.
Filtration is a commonly used technique in chemistry, biology, and other scientific disciplines to separate solids from liquids. It is also used in everyday life, for example, when making coffee or tea, or when using a water filter to remove impurities from drinking water.
