Abstract: The co-generation of hydrogen 11 from water 8 produced during pressure driven water desalination/filtration processes, such as reverse osmosis, forward osmosis, pressure retarded osmosis or ultrafiltration. A small part of feed, raw saline solution and/or permeate involved in a desalination/filtration processes is subjected to electrolysis thereby splitting the water to produce hydrogen. This is achieved by the provision of novel RO type semi-permeable membranes and UF type membrane that incorporate electrodes 9, 10 within the membrane to allow splitting of the water via electrolysis.

Abstract: Disclosed herein is a forward osmosis module for concentration and/or crystallization salts from an aqueous feed solution, the feed solution including seeds that surround an open semi-permeable membrane having free membrane portions forming an enclosure with a distribution pipe that introduces draw solution inside said enclosure. The feed solution penetrates into the enclosure as permeate from the feed side of the membrane to the draw solution side according to a Forward Osmosis process based on net driving pressure. The draw solution with permeate is evacuated from the enclosure via an outlet. A generator applies, at least periodically, a plurality of directional gauge pressure strokes PGs, directed from at least one of the draw solution inlet and outlet thereby effecting mechanical shaking of the free membrane portions for detachment of foulant.

Abstract: A large scale water desalination process for producing at least 100,000 m3/day of product water. Feed water is passed through a high pressure pump driven by at least one steam turbine capable of producing at least 1 MW of energy, the pressurized feed water passing through at least one reverse osmosis membrane to provide a residual brine stream and a product water. A start-up step slowly increases pressure in the membrane at a maximum rate of 12 psi (8.3 Newtons/cm2; 0.08 MPa) per second by rotation of the turbine driven high pressure pump at a maximum rate of 30 RPM to slowly increase pressure on the membrane to a predetermined operational pressure and controlling the operational pressure following the start-up step by rotation of the high pressure pump between 500 RPM and 5000 RPM dependent on the pressure applied by the steam turbine.
