Abstract: The invention relates to a separation apparatus for separating a liquid from a solution, in particular fresh water from seawater. The separation apparatus comprises an evaporation space in which operatively an amount of the solution is present from which a liquid vapor evaporates under the influence of heat. The separation apparatus further comprises a condensation space which is in connection with the evaporation space via a condensation tube and which is arranged for condensing liquid vapor. The separation apparatus also comprises a flow-through device for transporting the liquid vapor from the evaporation space to the condensation space, wherein the flow-through device is arranged for intermittently transporting the liquid vapor.
