Abstract
A desalination apparatus and a method of desalinating thereof, wherein the desalination apparatus comprises a perforated vessel and at least one engineered semi-permeable membrane that covers perforations on the perforated vessel, wherein the desalination apparatus forms a purified water from saline water when submerged in the saline water to a depth of 50-250 m to create sufficient pressure differential on both sides of the engineered semi-permeable membrane, wherein low-saline water flows through the engineered semi-permeable membrane and collected within an internal cavity of the desalination apparatus. Various embodiments of the desalination apparatus and the method of desalinating are also provided.
Claims20
A desalination apparatus, comprising:
- a vessel with an internal cavity, a port located proximal to a top of the vessel, and a valve that is attached to the port;
- a plurality of perforations on at least a portion of the vessel, wherein the plurality of perforations fluidly connect the internal cavity to an exterior of the vessel;
- a semi-permeable membrane that is secured on an external surface of the vessel and covers the plurality of perforations, wherein the semi-permeable membrane is selectively permeable to water;
- and
- a detachable vacuum pump that is connected to the port via a fluid line, wherein the detachable vacuum pump is configured to reduce a pressure within the internal cavity, and
- wherein the desalination apparatus is configured to form a purified water from saline water at a depth in the range of 30-150 m below a surface of the saline water.
