Filtration is a process involving the separation of particles or substances from a fluid or gas by passing it through a porous medium. This medium, commonly a filter or membrane, selectively allows certain components to pass while retaining others based on size, physical characteristics, or chemical properties. Widely applied in diverse fields, filtration ensures the purification of water by removing impurities, contributes to air purification for improved quality, aids in chemical processing by separating solids from liquids or gases, and finds application in biological processes for isolating specific components. This fundamental technique serves to enhance the quality, cleanliness, and safety of liquids and gases across various industrial, environmental, and scientific domains.
