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

Patent number: 8099958Abstract: A process for driving a prime mover, said process comprising a) positioning a selective membrane between a liquid and a solution having a higher osmotic potential than the liquid, such that the solution becomes pressurized by the influx of liquid across the membrane, b) using the pressure generated in the solution to drive a prime mover, c) recovering the solution, d) separating at least some of the solvent from the solution to form a residual product, and e) recycling the separated solvent and/or the residual product of step d) to step a).Type: GrantFiled: September 29, 2008Date of Patent: January 24, 2012Assignee: Surrey Aquatechnology LimitedInventors: Abdulsalam Al-Mayahi, Adel Sharif

Publication number: 20110226698Abstract: A novel dynamic filtration method and apparatus reduce the bio fouling and the scaling on the membrane surface during separation processes. A membrane separator is rotated while receiving feed to be separated into a component and waste. Because of the reduction in bio fouling and scaling on the membrane surface, the useful lives of RO and NF membranes may increase significantly, along with energy savings.Type: ApplicationFiled: November 19, 2010Publication date: September 22, 2011Inventors: Abdulsalam AL-MAYAHI, Mohammed Aljohani
