Filtration is a process used to separate solids from liquids or gases using a medium with pores of a specific size. The medium can be a membrane, a filter paper, or other porous materials. The process is widely used in various industries, including water treatment, pharmaceuticals, and food processing.

The filtration process involves passing a mixture through a filter medium. The particles or impurities that are larger than the pore size of the filter medium are retained, while the smaller particles or the liquid/gas pass through. The efficiency of filtration depends on the pore size of the filter medium and the size of the particles to be removed.

There are different types of filtration methods, including dead-end filtration, cross-flow filtration, and tangential flow filtration. Dead-end filtration is the simplest method, where the mixture is passed through a filter medium in a single direction. Cross-flow filtration and tangential flow filtration involve a continuous flow of the mixture parallel to the filter medium, which helps to prevent the buildup of particles on the filter surface.

Filtration is an essential process in many industries, as it helps to remove impurities and contaminants, ensuring the quality and purity of the final product. It is also used in environmental applications, such as wastewater treatment, to remove pollutants and improve water quality.
