separation of solids or liquids from a liquid or gas by using a barrier with holes smaller than particles being separated
Filtration, also known as filtering, is a widely used method of separating
solids from gases
solids from liquid
liquids from other liquids
Filtration uses a filter. This acts like a sieve to separate insoluble substances. A filter is a barrier with many, many smal l holes (often microscopic in size) in it. These holes are smaller than the particles being separated and so these particles get caught in the filter. However, smaller particles will pass straight through
