Physical Filtration
Physical filtration is a process of separating solid particles from a fluid or gas by passing it through a porous material. In the context of space and astronautical engineering, physical filtration is used to remove contaminants from air and water systems in spacecraft and space stations. The filtration system typically consists of a filter medium, such as activated carbon or a membrane, which traps particles and allows the clean fluid or gas to pass through. Physical filtration is an important aspect of maintaining a safe and habitable environment for astronauts in space, as it helps to prevent the spread of harmful microorganisms and pollutants. It is also used in the design of life support systems for long-duration space missions, where the recycling of air and water is essential for sustaining human life.
