Filtration is a process used to separate solids from liquids or gases by passing the mixture through a filter medium that allows the liquid or gas to pass through, but retains the solid particles. The process of filtration can be used to remove impurities, purify liquids or gases, or to separate particles based on size or other physical characteristics. There are several different types of filtration processes, including gravity filtration, pressure filtration, and vacuum filtration, and various types of filter media can be used, such as sand, gravel, activated carbon, or ceramic. Filtration is widely used in a variety of applications, including water treatment, beer brewing, medical treatment, and aerospace engineering.
