Vacuum membrane distillation
Vacuum membrane distillation is a separation process that uses a heated, porous membrane to allow only water vapor to pass through, leaving behind impurities and contaminants. By applying a vacuum on the permeate side, the vapor is drawn through the membrane more efficiently at lower temperatures. This method effectively purifies water, especially when dealing with heat-sensitive substances or contaminated sources, using less energy than traditional distillation. It combines membrane filtration and distillation principles, enabling clean water production even from complex or salty feedwaters.
