Abstract
A deep ocean desalination system that uses hydrostatic pressure to reverse osmosis the seawater. The membrane structure is deployed to a predetermined ocean depth and includes a submersible pump system.
Claims5
A desalination system capable of producing fresh water from sea water extracted from a predetermined depth below the ocean surface comprising:
- a reverse osmosis system comprising:
- a membrane-enclosed container having a polyhedron shape following a Hoberman Sphere, wherein all of the faces of the polyhedron shape are the same shape and size and each face of the polyhedron shape is encompassed by a semi-permeable membrane, wherein the membrane-enclosed container has an exterior surface area and an internal cavity;
- and
- a submersible pump operatively connected to a riser, wherein, once deployed to the predetermined depth, the internal cavity has a first pressure at or near atmospheric pressure and the sea water surrounding the membrane-enclosed container has a second pressure different from the first pressure thus creating a pressure differential that draws fresh water into the internal cavity through each face of the membrane-enclosed container while restricting dissolved solids and salts in the sea water from passing through each face of the membrane-enclosed container, and the pump delivers the fresh water to the riser,
- wherein the riser is operatively connected to a power supply above the ocean surface, wherein the riser deploys the reverse osmosis system to the predetermined depth, wherein the predetermined depth is between about 350 meters and 750 meters, and wherein the pump is operatively connected to the power supply via its operative connection to the riser;
- and
- a pipe operatively connected to the riser to deliver the fresh water received from the riser to a intended destination;
- at least one buoy attached to the membrane-enclosed container;
- and
- a mooring system connected to the membrane-enclosed container to maintain the reverse osmosis system at the predetermined depth after deployment.
