Dilute brine desalination apparatus using a method

Object of the present invention to provide a method of using a dilute brine desalination apparatus. Desalination apparatus includes a permeable sheet inside the container, water repellent granular layer, the reservoir layer, the reservoir layer is located in a lower portion of the container, breathable water repellent sheet sandwiched between the particle layer and the reservoir layer. Permeable sheet includes a through-hole, the water-repellent layer composed of dense particles of a plurality of water-repellent particles, the particle surface is provided with water-repellent hydrophobic film. By step to dilute saline: Saline was infused into the vessel, so that the brine step disposed on the surface of the water repellent particle layer; heating the brine, so that the above-described step of forming the brine evaporator water vapor; and a vapor liquefaction, resulting in the reservoir layer freshwater process.
