  • Patent number: 9873618
    Abstract: In a desalination system, a water-repellent particle layer is provided at a lower portion of a water tank and composed of water-repellent particles. A devolatilizing layer is provided below the layer. Liquid is provided in the tank and is heated for evaporation, and obtained vapor passes through the particle layer and is liquefied at the devolatilizing layer, so that freshwater is obtained from the liquid. The particle layer includes a first and a second particle layers composed of discriminable first and second particles. A particle measuring unit measures an amount of the second water-repellent particles. A decision unit decides whether or not the measured amount of the second water-repellent particles is equal to or more than a predetermined value. A controller alerts when the decision unit decides that the amount of the second particles is equal to or more than the predetermined value.

  • Patent number: 9409819
    Abstract: A water repellent sand mixture includes at least water repellent sand and cement at a weight ratio of 2% or more and 5% or less relative to the water repellent sand. The mixture achieves condensation between the water repellent sand particles by the hydration reaction of the cement, which improves dynamic stability. The mixture can be kept in a block shape due to such improved dynamic stability, water repellency, and less slidable surfaces of the sand particles.
