| 20120118826 | DESALINATION SYSTEM - A desalination system based on forward osmosis, that uses a draw solution at high osmotic and gauge pressures to generate mechanical power from the expansion of the draw solution due to water extracted from feed water through a semi-permeable membrane. The extracted water is produced during the regeneration of the draw solution. The generated power may be used to desalinate additional feed water, e.g. via reverse osmosis, such that most power needed for the reverse osmosis is supplied from the expanding draw solution, e.g. via a work exchanger. After power recovery, partly dilute draw solution may be used to extract additional water from feed water via an additional forward osmosis module. | 05-17-2012 |
| 20120111785 | VERTICAL DESALINATION ELEMENT - A vertical desalination element comprising a vertical pressure vessel (PV), membrane elements, and a loading mechanism for loading the membrane elements into the vertical PV. The vertical arrangement of the membrane elements and the vertical PV enhances air bubble percolation, increases construction efficiency and allow handling heavy membrane elements. The membrane elements may be loaded singly or groupwise, from either the upper or the lower end of the vertical PV. The loading mechanism may comprise various appliances and devices for supporting and securing the membrane elements, and may apply various ways of loading and releasing the membrane elements. | 05-10-2012 |
| 20110271712 | COOLING CRYSTALLIZER - A system and method for separating at least a part of the solids from brine having an initial temperature T | 11-10-2011 |
| 20110233044 | MULTI-EFFECT EVAPORATOR - A multi-effect evaporator, having an upstream and a downstream end, adapted for distillation of water. It comprises a plurality of effects connected in a series manner and arranged into groups. Each group has a common parallel water feed inlet adapted to supply all effects in the group with feed water. The evaporator further includes a main feed water line in fluid communication with the most upstream group. An array of heaters is disposed along the line, adapted for heating the feed water before its entry into the effects of the latter group. Each effect comprises means for forwarding the second outlet vapor into one of the heaters for heating the feed water. Each group comprises a pump adapted to extract the concentrate from the effects of the group and pump it into the common parallel water feed of an adjacent downstream group. | 09-29-2011 |
| 20110108484 | METHOD OF IMPROVING PERFORMANCE OF A REVERSE OSMOSIS SYSTEM FOR SEAWATER DESALINATION, AND MODIFIED REVERSE OSMOSIS SYSTEM OBTAINED THEREBY - A method for improving performance of an original reverse osmosis system for seawater desalination, the original system comprising a high pressure pump, a reverse osmosis membrane arrangement, a pump hydraulic line and a turbine hydraulic line, the method comprising operating the motor at a power lower than a normal operation power; providing an energy recovery device; splitting new brine flow to a first brine flow; supplying an additional seawater; providing a booster pump; providing an energy recovery device hydraulic line; providing a first booster pump hydraulic line; and providing a second booster pump hydraulic line. | 05-12-2011 |

| 20100282676 | DESALINATION SYSTEM AND ELEMENTS THEREOF - According to one aspect of the present invention, there is provided a desalination system comprising a plurality of elongated pressure vessels (PV). Each PV has a longitudinal axis, oriented such that the longitudinal axis thereof is of a vertical orientation. Each of the PVs is adapted to receive therein a plurality n of desalination membranes. The membranes located above the lowermost membrane within the PV have a total weight allowing them to function as a mechanism limiting axial expansion of the lowermost membrane, whereby the PV is free of any additional limiting mechanism. | 11-11-2010 |
