摘要: A method of treating a fluid comprises introducing a feed fluid stream comprising multiple materials to first side of a semi-permeable membrane. A draw fluid stream having a higher temperature than the feed fluid stream is introduced to second, opposing side of the semi-permeable membrane to form a thermal gradient across the semi-permeable membrane. One or more of the multiple materials of the feed fluid stream is drawn through the semi-permeable membrane and into the draw fluid stream via thermal gradient osmosis. A fluid treatment system and a thermal gradient osmosis apparatus are also described.

摘要: The present invention relates to processes and systems for ammonia recovery and/or acid-gas separation. In some embodiments, a system for acid gas separation may be integrated with an ammonia abatement cycle employing a high temperature absorber. In some embodiments, a system for acid gas separation may employ a higher temperature absorber due to the lower energy consumption and cost of the integrated ammonia abatement cycle. Advantageously, heat may be recovered from the absorber to power at least a portion of any acid gas desorption in the process. Reverse osmosis or other membranes may be employed.

摘要: An example water purification system for purifying high concentration feed solutions includes a high rejection forward osmosis module, one or more low rejection modules, and a high rejection reverse osmosis module. The low rejection modules may have different rejection levels. The system may be pressurized by one or more pumps. One or more of the low rejection modules may include one or more nanofiltration (NF) membranes. The draw solution may comprise a monovalent salt, a multivalent salt, or a combination of both.

摘要: Systems and processes for purifying and concentrating a liquid feed stream are disclosed. In the systems, the concentrated liquid output from the high pressure side of a reverse osmosis stage is used as the draw solution in the low pressure side of the reverse osmosis stage in a configuration called osmotically assisted reverse osmosis. This reduces the osmotic pressure differential across the membrane, permitting high solute concentrations to be obtained, hastening the purification of the liquid. Reduced system pressures are also obtained by arranging multiple osmotically assisted reverse osmosis stages in a cross-current arrangement. Overall system energy consumption is reduced compared to conventional thermal processes for high concentration streams.

摘要: An ocean alkalinity enhancement (OAE) system that reduces atmospheric CO2 and mitigates ocean acidification by electrochemically processing feedstock solution (e.g., seawater or brine) to generate an alkalinity product that is then supplied to the ocean. The OAE system includes a base-generating device and a control circuit disposed within a modular system housing deployed near a salt feedstock. The base-generating device (e.g., a bipolar electrodialysis (BPED) system) generates a base substance that is then used to generate the ocean alkalinity product. The control circuit controls the base-generating device such that the alkalinity product is supplied to the ocean only when (1) sufficient low/zero-carbon electricity is available, (2) it is safe to operate the base-generating device, and (3) supplying the alkalinity product will not endanger sea life. Modified BPED systems include features that facilitate autonomous system operations including enhanced maintenance cycle operations and a reduced reliance on external fresh water sources.

摘要: The hybrid desalination system (10) includes a reverse osmosis filtration system (14), a forward osmosis filtration system (18), and a multi-effect distillation system (16). A condenser (12) receives seawater (S) and produces cooled seawater (CS). The cooled seawater (CS) is filtered by the reverse osmosis filtration system (14), which outputs a first brine reject stream (BR1) and a permeate stream (P). The multi-effect distillation system (16) outputs a second brine reject stream (BR2). A feed side (20) of the forward osmosis filtration system (18) receives the first brine reject stream (BR1), and the second brine reject stream (BR2) is received by the draw side (22), which outputs diluted brine (DB). The multi-effect distillation system (16) is in fluid communication with the forward osmosis filtration system (18) and recycles the diluted brine (DB). The multi-effect distillation system (16) outputs a return condensate (RC) and a pure water distillate (D).
