摘要： The present invention discloses a method and an apparatus for desalination of high-salt and high-concentration organic wastewater by coupling three membrane separation technologies. Wastewater is subjected to diffusion desalination to obtain diffusion desalination wastewater and diffusion desalination circulating water; the diffusion desalination circulating water is subjected to reverse osmosis to obtain pure water and high-concentration salt water; and the diffusion desalination wastewater is subjected to forward osmosis to obtain forward osmosis wastewater and forward osmosis circulating water, where the forward osmosis wastewater is desalted and concentrated wastewater.

摘要： A method and system of generating electrical power or hydrogen from thermal energy is disclosed. The method includes separating, by a selectively permeable membrane, a first saline solution from a second saline solution, receiving, by the first saline solution and/or the second saline solution, thermal energy from a heat source, and mixing the first saline solution and the second saline solution in a controlled manner, capturing at least some salinity-gradient energy as electrical power as the salinity difference between the first saline solution and the second saline solution decreases. The method further includes transferring, by a heat pump, thermal energy from the first saline solution to the second saline solution, causing the salinity difference between the first saline solution and the second saline solution to increase. The method may include a process of membrane distillation, forward osmosis, evaporation, electrodialysis, and/or salt decomposition for further energy efficiency and power generation.

摘要： Methods and systems are described that produce an ultra-high gravity alcoholic beverage from a high gravity alcoholic beverage stream using an efficient, low waste, combination reverse osmosis and forward osmosis system. Utilizing a reverse osmosis system prior to using a forward osmosis system in removing water content from a high gravity alcoholic beverage stream significantly reduces a draw solution load when compared to a process that utilizes a forward osmosis system alone or prior to using any other dewatering system.

摘要： An aqueous feed stream having a first total dissolved solids (TDS) level is flowed to a forward osmosis separator. The aqueous feed stream includes seawater. An aqueous draw stream having a second TDS level is flowed to the forward osmosis separator. The second TDS level is greater than the first TDS level. A disposal stream and an injection fluid stream is produced by the forward osmosis separator by allowing water to pass from the aqueous feed stream to the aqueous draw stream through a membrane of the forward osmosis separator based on a difference between the first TDS level and the seconds TDS level. The injection fluid stream is flowed from the osmosis separator to a subterranean formation.

摘要： A system and method for purifying water provides a feed solution water stream having a first osmotic pressure and a temperature T1 on a feed side of a semipermeable membrane. A draw solute stream has a temperature T2 and a second osmotic pressure higher than the first osmotic pressure. Water is mixed with the draw solution stream to produce a diluted draw solution stream having a temperature T3. Temperature T2 is higher than T1, and T3 is lower than T2. A solar panel has a heat exchanger in communication with the draw side and the solar panel has a temperature T4 higher than the temperature T3. The diluted draw solution stream passes into the heat exchanger to cool the solar panel. The diluted draw solution stream is heated and separated into purified water and recovered draw solution. The recovered draw solution passes to the membrane draw side for recycling.

摘要： In one embodiment, a renewable energy storage system includes a forward osmosis system, a hydro-turbine, and a separation (e.g., CEDI) system powered by one or more natural regenerating energy sources, such as wind or solar. In another embodiment, a renewable energy storage system includes a forward osmosis system, a hydro-turbine, a solar thermal heat exchanger through which the diluted osmotic draw solution can be directed for purposes of heating up the draw solution, and a solvent-water separator configured to separate the draw solution from the water. One example method includes drawing water across a forward osmosis membrane in a forward osmosis system such that the water drawn across the membrane dilutes an osmotic draw solution; directing the diluted osmotic draw solution to drive a hydro-turbine to produce energy; and separating the water from the draw solution using one or more natural regenerating energy sources.
