  • Patent number: 10571373
    Abstract: A method and system for enabling the determination of kinetic rates of reaction within a fluid of interest including directing fluid flow exiting a test bed to a multi-port switching valve. The multi-port switching valve switches the fluid to a number of channels connected to a number of interchangeable in-flow extraction cartridges. Analytes of interest from the fluid flow are captured on an extraction medium to accumulate over time. Rates are determined by (i) sequentially channeling the fluid through each of the plurality of flow paths for a preselected time duration, (ii) analyzing the extraction cartridges, and computing the kinetic rate of reaction.

  • Patent number: 10258926
    Abstract: A carrier gas and a combined feed liquid are directed through a humidifier, where water vaporizes from the combined feed liquid into the carrier gas, and through a dehumidifier, where the combined feed liquid cools the carrier gas to condense water from the carrier gas. At least a portion of the concentrated brine stream from the humidifier is directed through a pressure-retarded osmosis unit, while an initial feed solution is directed, in counter-flow, through the osmosis unit. Water from the initial feed solution flows through a membrane in the osmosis chamber into the concentrated brine stream to dilute and increase the volumetric flow rate of the brine stream. The diluted brine stream is extracted from the osmosis chamber and depressurized to produce power, while the concentrated initial feed solution is combined with the depressurized, diluted brine stream to form the combined feed liquid.

  • Patent number: 9839879
    Abstract: A forward osmosis membrane for seawater desalination and a method for preparing the same. The forward osmosis membrane has a composite membrane structure including a nonwoven fabric layer; a hydrophilic polymer layer; and a polyamide layer. The hydrophilic polymer layer formed on the nonwoven fabric layer facilitates an inflow of water from the feed water to the draw solution to enhance flux and realize high water permeability in the direction of osmosis. The polyamide layer not only secures contamination resistance and chemical resistance but also minimizes the back diffusion of salts of the draw solution in the direction of reverse osmosis. Hence, the forward osmosis membrane of the present invention is greatly useful for desalination of high-concentration seawater.

  • Patent number: 9433901
    Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.

  • Patent number: 8801934
    Abstract: Systems and methods for osmotically assisted desalination include using a pressurized concentrate from a pressure desalination process to pressurize a feed to the desalination process. The depressurized concentrate thereby produced is used as a draw solution for a pressure-retarded osmosis process. The pressure-retarded osmosis unit produces a pressurized draw solution stream that is used to pressurize another feed to the desalination process. In one example, the feed to the pressure-retarded osmosis process is impaired water.

  • Patent number: 8790515
    Abstract: A method of filtering solids from a liquid suspension comprising providing a pressure differential across the walls of permeable, hollow membranes (5) immersed in the liquid suspension contained in a vessel (8), the liquid suspension being applied to the outer surface of the porous hollow membrane (5) to induce and sustain filtration through the membrane walls. Some of the liquid suspension passes through the walls of the membranes (5) to be drawn off as permeate from the hollow membrane lumens, and at least some of the solids are retained on or in the hollow membranes or otherwise as suspended solids within the liquid surrounding the membranes (5).

  • Publication number: 20140183134
    Abstract: Described herein is a structure for a permeate spacer for use in spiral wound osmosis membrane elements, having at least two sets of parallel ribs, wherein the ribs in the first set are oriented at about a 90 degree angle to the ribs in the second set. The permeate spacer is used by sandwiching it inside a membrane envelope or leaf, and is particularly useful for non-pressure-driven processes, such as forward osmosis (FO) and pressure-reduced osmosis (PRO).

    Abstract: An example separation system includes a stack of membrane plate assemblies. An example membrane plate assembly may include membranes bonded to opposite sides of a spacer plate. The spacer plate may include a first opening in fluid communication with a region between the membranes, and a second opening in fluid communication with a region between membrane plate assemblies. Adjacent membrane plate assemblies in the stack may have alternating orientations such that bonding areas for adjacent membranes in the stack may be staggered. Accordingly, two isolated flows may be provided which may be orthogonal from one another.

  • Patent number: 8753514
    Abstract: An energy efficient desalination process that does not produce waste products involves the extraction of water from a first solution, such as seawater, by using a second concentrated solution to draw the water from the first solution across a semi-permeable membrane. By manipulating the equilibrium of the soluble and insoluble species of solute within the second solution in favor of the soluble species of the solute, a saturated second solution can be used to generate osmotic pressure on the first solution. Also, by adjusting the equilibrium in favor of the less soluble species after the water has been drawn from the first solution, a portion of the solute can easily be precipitated out. Heating the second solution decomposes the solute into its constituent gases. The constituent gases and precipitated solute may be recycled through the process to affect the changes in equilibrium and eliminate waste products.

  • Publication number: 20140158622
    Abstract: The present disclosure relates to a water recovery method and an FO draw solution that reduce the energy consumption required for water recovery, increase the osmotic pressure of a draw solution, recover the water from a DS mixed solution relatively easily, and reduce a solute that remains in the water, and simultaneously reduce fouling of the FO membrane. The water recovery method may include inflowing water into a draw solution by partitioning a feed solution including water and a draw solution, including a basic temperature-sensitive polymer and an acidic gas dissolved therein and having higher osmotic pressure than the feed solution, with a forward osmosis membrane.
