Abstract: A desalination apparatus that includes: a water-repellent particle layer that is located below a water tank, contains water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the water tank, the water tank being a space for storing the liquid; and a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water. The water-repellent particle layer includes: a first layer that contains first water-repellent particles among the water-repellent particles, and faces the water tank; and a second layer that contains second water-repellent particles among the water-repellent particles, and is provided below the first layer. The second water-repellent particles have a larger average particle size than the first water-repellent particles.

Abstract: A desalination method includes: introducing a liquid to a reservoir layer to place the liquid above a water-repellent particle layer; heating and evaporating the liquid placed above the water-repellent particle layer to generate water vapor and deposit impurities on the sheet; liquefying the water vapor by a liquefying layer to obtain fresh water; and removing the sheet on which the impurities have been deposited from a desalination apparatus.

Abstract: The desalination apparatus according to the present disclosure includes: a water-repellent particle layer that is located below a water tank, contains water-repellent particles, and allows passage of water vapor generated by evaporation of the liquid stored in the water tank, the water tank being a space for storing the liquid; and a liquefying layer that is located below the water-repellent particle layer, and liquefies the water vapor that has passed through the water-repellent particle layer to obtain the fresh water. The water-repellent particle layer includes an anti-migration layer provided as a surface layer that faces the water tank and containing anti-migration particles. Each of the anti-migration particles has a higher aspect ratio than the water-repellent particles, the aspect ratio being a value obtained by dividing a length in a major axis direction by a length in a minor axis direction.

Abstract: A water amount controlling method according to the present disclosure includes: opening a discharge valve that discharges a liquid from a water tank if an impurity concentration is higher than or equal to a first reference value, and opening a sluice gate that introduces the liquid to the water tank a predetermined period after opening the discharge valve, the first reference value being lower than a saturation concentration; throttling the discharge valve and the sluice gate if the impurity concentration is higher than or equal to a second reference value and the temperature is lower than or equal to a third reference value, the second reference value being lower than the first reference value; and closing the discharge valve if the impurity concentration is lower than the second reference value, and closing the sluice gate a predetermined period after closing the discharge valve.
