Abstract: A method and a 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 and system may include a regeneration process, such as membrane distillation, forward osmosis, electrodialysis, salt evaporation and/or salt decomposition.

Abstract: A new and innovative power and treated water co-generation system is provided that includes a modified Kalina cycle and a forward osmosis (FO) membrane. The Kalina cycle of the provided system is used for power production, whereas the system's FO process is used for water production. The provided system modifies a typical Kalina cycle to include a more efficient and relatively low-temperature heat source, while still utilizing the same working fluid, which is ammonia-water. The draw solution for the provided system's FO process is also ammonia-water, which is known and efficient for desalination and wastewater treatment. In some aspects, the working fluid of the system may be a specific ammonia-water composition including between 30-95% ammonia. The presently disclosed system combines the Kalina process and the FO process into an improved and innovative heat integration system to minimize energy requirements and enable operation at both small and large scales.

Abstract: A membrane distillation apparatus includes a housing and an impeller. The housing includes a hot medium compartment, a cold medium compartment, an air gap compartment, a membrane, and a thermally conductive plate. The hot medium compartment includes a hot medium inlet configured to receive a hot medium stream including water. The cold medium compartment includes a cold medium inlet configured to receive a cold medium stream. The membrane defines pores that are sized to allow water vapor originating from the hot medium stream to pass from the hot medium compartment through the membrane to the air gap compartment. The thermally conductive plate and the cold medium stream are cooperatively configured to condense the water vapor from the hot medium stream. The air gap compartment is substantially filled with air and includes a permeate outlet configured to discharge the condensed water vapor. The impeller is disposed within the air gap compartment.

Abstract: A distillation device and method of manufacturing a distillation device is disclosed. The distillation device includes at least one spiral wound membrane distillation (MD) unit. The spiral wound MD unit includes a perforated center tube concentric to a cylindrical housing and a plurality of effects spirally wound around the center tube. Each of the effects include a vapor permeable membrane, a feed spacer disposed on the vapor permeable membrane, a permeate spacer, and a heat exchange film. The permeate spacer is disposed between the vapor permeable membrane and the heat exchange film. Distillation of a feed fluid by the plurality of effects deposits a condensate fluid into the center tube.

Abstract: 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.

Abstract: A water treatment system includes a reverse osmosis membrane device, an electrodeionization device that is located downstream of the reverse osmosis membrane device, a first heat exchanger that is located upstream of the reverse osmosis membrane device and that adjusts the temperature of the water supplied to the reverse osmosis membrane device according to the temperature of raw water supplied to the water treatment system, and a second heat exchanger that is located between the reverse osmosis membrane device and the electrodeionization device and that cools the water supplied to the electrodeionization device. One of the first heat exchanger and the second heat exchanger is an internal heat exchanger that exchanges heat inside the water treatment system, and the other is an external heat exchanger that exchanges heat with the outside of the water treatment system.
