Membrane Separation
Membrane separation is a process that uses a semi-permeable membrane to separate and purify different components of a fluid mixture. In the context of space and astronautical engineering, membrane separation is used for water purification, gas separation, and air revitalization. Membrane separation is a critical technology for long-duration space missions, where the recycling of water and air is essential for sustaining life. The membrane separation process is based on the principle of selective permeation, where the membrane allows certain components to pass through while retaining others. The separation efficiency of the membrane depends on its pore size, surface area, and selectivity. Membrane separation is a cost-effective and energy-efficient technology that has a wide range of applications in space exploration and habitation.
