20150232351 | OSMOTICALLY DRIVEN MEMBRANE PROCESSES AND SYSTEMS AND METHODS FOR DRAW SOLUTE RECOVERY - The invention relates to osmotically driven membrane processes and systems and methods for recovering draw solutes in the osmotically driven membrane processes. Osmotically driven membrane processes involve the extraction of a solvent from a first solution to concentrate solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Draw solute recovery may be carried out by various means including with the use of a membrane device. The draw solute recovery may also include the use of multi-stage solute recovery using distillation columns and/or membranes, where the recovery may be assisted by a heat pump. | 08-20-2015 |
20150014232 | MEMBRANE MODULES - The invention relates to membrane modules and applications therefor. In particular, the invention relates to the construction of membrane modules for use in forward osmosis, heat exchange, and distillation processes. | 01-15-2015 |
20140263025 | MEMBRANE MODULES - The invention relates to membranes, membrane modules, and applications therefor. In particular, the invention relates to the construction of membranes and membrane modules for use in osmotically driven membrane processes. | 09-18-2014 |
20140238937 | SYSTEMS AND METHODS FOR IMPROVING FLUX IN OSMOTICALLY DRIVEN MEMBRANE SYSTEMS - The invention relates to improving flux in osmotically driven membrane systems by promoting and controlling the growth of biofilms on a surface of the membrane. | 08-28-2014 |
20120273417 | FORWARD OSMOSIS SEPARATION PROCESSES - Separation processes using engineered osmosis are disclosed generally involving the extraction of solvent from a first solution to concentrate solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Enhanced efficiency may result from using low grade waste heat from industrial or commercial sources. | 11-01-2012 |
20120267306 | OSMOTIC SEPARATION SYSTEMS AND METHODS - Separation processes using engineered osmosis are disclosed generally involving the extraction of solvent from a first solution to concentrate solute by using a second concentrated solution to draw the solvent from the first solution across a semi-permeable membrane. Enhanced efficiency may result from using low grade waste heat from industrial or commercial sources. | 10-25-2012 |
20120234758 | FORWARD OSMOSIS MEMBRANES - Forward osmosis membranes include an active layer and a thin support layer. A bilayer substrate including a removable backing layer may allow forward osmosis membranes with reduced supporting layer thickness to be processed on existing manufacturing lines. | 09-20-2012 |
20120073795 | THIN FILM COMPOSITE HEAT EXCHANGERS - The invention generally relates to thin film composite heat exchangers and methods of making thin film composite heat exchangers. The heat exchangers can be made with polymers or other materials including, but not limited to, inorganic materials such as silicon, clay, ceramic, brick, or metal. Heat exchangers in accordance with the invention may be made of a material that is non-corrosive, durable, and that may be applied in a thin coating so as to minimize resistance to heat transfer and material costs. | 03-29-2012 |
