PROBLEM TO BE SOLVED: To provide a seawater desalination apparatus which can recover more energy and reduce a used energy amount in the whole system.SOLUTION: A seawater desalination apparatus for separating seawater into fresh water and concentrated seawater is equipped with an energy recovery device. The energy recovery device is provided with a permeable membrane, concentrated seawater is brought into contact with one side of the permeable membrane, seawater is brought into contact with the other side of the permeable membrane, and energy is recovered and used from a water flow caused by percolation of seawater toward the concentrated-seawater side. |
