Original Title South Korea's Seawater Desalination Nano Film Lasts Long Filtration Effect Is Still as High as 9999% After One Month "Water water everywhere but not a drop to drink" the ocean is like this but we can use new technology to convert seawater into drinkable fresh water recently South Korean scientists have developed a highly efficient new nanofiber membrane and after 30 days of use the effect of filtering saline is still 9999% Seawater desalination is divided into reverse osmosis and distillation in which reverse osmosis uses pressure difference and "selective penetration" reverse wiped film evaporator osmosis membrane to separate water and salt Fresh water and seawater are placed on both sides of the membrane Due to different osmotic pressures water molecules will flow from fresh water to seawater until the two sides complete the equilibrium state; Distillation is done by heating seawater separating the salt from the water vapor and condensing the water vapor into fresh water

This method requires a large amount of heat energy and is usually combined with a thermal power plant The team of Korea Institute of Civil Engineering and Construction Engineering Technology (KICT) a state-owned company in South Korea focuses on Membrane Distillation (MD) this time A hydrophobic membrane is selected as the separator One side is the heating saline thin film distillation
