Patent number: 8449774Abstract: A process for separating dissolved components from a solution, said process comprising a) introducing a first solution into a solar pond and irradiating the solution with solar energy, such that temperature and concentration gradients are established, whereby the temperature and concentration of solute at the base of the pond is greater than the temperature and concentration of solute at the surface of the pond, b) introducing a portion of the first solution from the pond into a first osmosis unit, and contacting the portion with one side of a selectively permeable membrane, c) contacting the other side of the selectively permeable membrane with a second solution having a lower solute concentration than the portion of first solution from the pond, such that solvent from the second solution passes across the membrane to dilute and pressurize the portion of first solution, d) removing the diluted portion of first solution from the first osmosis unit, and e) using the pressure generated in the diluted portion ofType: GrantFiled: October 15, 2007Date of Patent: May 28, 2013Assignee: Surrey Aquatechnology LimitedInventor: Adel Sharif

Patent number: 8221629Abstract: A process for removing a solvent from a first solution, said process comprising positioning a selective membrane between the first solution and a second solution having a higher osmotic potential than the first solution, such that solvent from the first solution passes across the membrane to dilute the second solution, and extracting solvent from the second solution, wherein the membrane has an average pore size of at least 10 Angstroms, and wherein the second solution contains solute species that are too large to pass through the pores of the membrane.Type: GrantFiled: January 24, 2011Date of Patent: July 17, 2012Assignee: Surrey Aquatechnology LimitedInventors: Abdulsalam Al-Mayahi, Adel Sharif
