membrane distillation

Membrane distillation is a water purification process that uses a special porous membrane to separate water from contaminants. It works by heating water on one side of the membrane, creating vapor that passes through the membrane's tiny pores. On the other side, cooler air helps condense the vapor back into liquid water. This process can effectively remove salts, pollutants, and other impurities, making it useful for desalination (turning salty water into fresh water) and treating industrial wastewater. It's energy-efficient and can use low-grade heat sources, making it a promising technology for sustainable water purification.
