Abstract

The invention relates to an arrangement meant for seawater or brackish water desalination, comprising a reverse-osmosis desalination unit 20 and a natural or artificial or adequately- modified lake 10 containing a high-concentration salt solution. A supply of high-concentration salt solution current flows out from said lake and returns thereto in a lower salt concentration state. The lake’s water evaporation -which is mainly achieved by solar energy-ensures the approximately constant long-term salt concentration. Practically, the lake 10 operates as a low-cost solar collector. The required compression of the seawater or brackish water that enter from one side of the semi-permeable membranes of the pressure containers 22 of the reverse-osmosis desalination unit 20 is obtained by displacement due to the volume increase of the high-concentration salt solution current coming from the lake 10 and returning thereto under a diluted condition. The increase of the high-concentration salt solution current occurs under high-pressure conditions as this current absorbs water from another seawater current through semi-permeable membranes contained in the respective pressure containers of an additional osmosis unit 40 which operates under the direct-osmosis principle.
