Abstract: A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A solids membrane separation system removes solids from the influent water being processed. A pervaporation (PV) system eliminates liquid impurities from the influent water being processed.

Abstract: Embodiments described herein relate to methods and systems for dewatering alcoholic solutions via forward osmosis.

Abstract: Examples disclosed herein relate to methods and systems for controllably removing one or more solutes from a solution. Examples disclosed herein relate to methods and systems for removing water from alcoholic beverages.

Abstract: A high salinity water purification system and process, including a forward osmosis system and a reverse osmosis or nanofiltration system. A concentrated brine of a zinc or iron complex combined with a salt or acid draws pure water across the FO membrane from the influent water. The diluted brine is pumped through a vessel holding an anionic adsorption media to remove the zinc or iron complex and the resultant brine is passed through the RO or nanofiltration system to obtain purified water and a concentrated brine stream. The adsorption media is regenerated by a rinse cycle using fresh water or water from the RO system, removing the zinc or iron complex adhered to the media. The resultant brine is stored and mixed with the output of the RO system. Charged membrane can be used as a standalone membrane in FO process or in combination with resin or resin embedded membrane.

Abstract: Embodiments described herein relate to methods and systems for dewatering alcoholic solutions via forward osmosis, where the concentration of alcohol in the draw stream is equal to or greater than the concentration of the alcohol in the feed stream. As the feed stream is concentrated the alcohol is retained in the feed stream.

Abstract: Membranes for fluid separation are disclosed. These membranes have a matrix layer sandwiched between an active layer and a porous support layer. The matrix layer includes 1-D nanoparticles that are vertically aligned in a porous polymer matrix, and which substantially extend through the matrix layer. The active layer provides species-specific transport, while the support layer provides mechanical support. A matrix layer of this type has favorable surface morphology for forming the active layer. Furthermore, the pores that form in the matrix layer tend to be smaller and more evenly distributed as a result of the presence of aligned 1-D nanoparticles. Improved performance of separation membranes of this type is attributed to these effects.

Abstract: Forward osmosis membranes having a hydrophilic support layer and a polyamide rejection layer in a thin film composite membrane are considered. Preferred support layer materials include aramid polymers and PVDF. A woven or non-woven mesh can be incorporated into the support layer to improve handling properties of the membrane. Flat sheet and hollow fiber configurations are possible. Antifouling techniques are provided. The polyamide layer can be formed on the hydrophilic support layer by interfacial polymerization. Applications include forward osmosis and pressure retarded osmosis applications, such as industrial product and/or waste concentration, hydration bags, energy/pressure generation, and controlled delivery of chemicals (e.g., for pharmaceutical applications).

Abstract: Azidoaryl-substituted cyclooctene monomers and synthesized and used in the preparation of various copolymers. Among these copolymers are those prepared from ring-opening metathesis polymerization of cyclooctene, polyethylene glycol-substituted cyclooctene, and azidoaryl-substituted cyclooctene. These copolymers are useful in the formation of crosslinked films that reduce fouling of water purification membranes.
