    摘要: Devices, methods, and systems for producing a concentrated feed stream and a diluted feed stream using a solute stream provided to the low pressure side of the semi-permeable membrane during a reverse osmosis process. The process includes providing a semipermeable membrane having a first side and a second side and introducing a first feed solution stream on the first side of the membrane and a second feed solution stream on the second side, wherein the osmotic pressure of the of the first feed solution stream is greater than or equal to the osmotic pressure of the second feed solution stream. The process further includes exerting hydrostatic pressure on the first side of the membrane such that solvent passes from the first side to the second side thereby producing a concentrated first feed solution stream and a diluted second feed solution stream. Devices and systems for performing the processes are provided.

    摘要: Embodiments disclosed herein are directed to methods and systems for treating wastewater via forward osmosis. By way of example, the methods and systems disclosed herein may be used to filter one or more precipitated salts and/or other particles from wastewater generated by power plants such as flue gas wastewater, oil and gas wastewater, and other industrial processes. For example, the methods and systems disclosed herein may be used to filter one or more precipitated salts from a wastewater feed concentrate formed during the forward osmosis process that is recirculated through at least one membrane module to continue the forward osmosis process. Filtering the one or more precipitated salts from the wastewater feed concentrate helps limit clogging of open channel feed spacer(s) of the at least one membrane module.

    摘要: Provided herein are osmotic desalination methods and associated systems. According to certain embodiments, multiple osmotic membranes may be used to perform a series of osmosis steps, such that an output stream having a relatively high water purity - compared to a water purity of an aqueous feed stream - is produced. In some embodiments, multiple draw streams can be used to produce aqueous product streams having sequentially higher purities of water. Certain embodiments are related to osmotic desalination systems and methods in which forward osmosis is used to produce a first product stream having a relatively high water purity relative to an aqueous feed stream, and reverse osmosis is used to perform a second step (and/or additional steps) on the first product stream. In some embodiments, multiple reverse osmosis steps can be used in series to perform a net desalination process.

    摘要: The present invention relates to a novel forward osmosis (FO) process for dewatering of a variety of feed solution using low water activity and high osmotic pressure deep eutectic solvent with and without dispersed magnetic nanoparticles as draw solution. In particular, choline chloride-ethylene glycol, choline chloride- glycerol, Fe304 dispersed in former and latter were utilized as draw solution in FO for one step desalination of brackish and seawater, water recovery from effluent of leather and dye industries, protein and DNA concentration at room temperature. Owing to very low freezing point, the diluted draw solution after FO was recovered through phase separation by chilling at Ca. -10 °C with concomitant production of usable water. Although the present invention focused on specific DES and dispersion of Fe3O4 as magnetic nanoparticles but use of other DES having high osmotic pressure and low freezing point and other magnetic nanoparticles dispersion are logical extension of present invention.
