摘要： A high efficiency ejector for use in desalination applications includes a mixing duct, a boiler, a primary high pressure steam duct connected to a plurality of inner supersonic nozzles and a plurality of outer supersonic nozzles. The inner nozzles and the outer nozzles have axes that are canted radially with respect to each other, in an asymmetric arrangement or in a 2-dimensional geometric arrangement. The inner nozzles and the outer nozzles each communicates with the mixing duct. A secondary duct communicates upstream with the boiler, and downstream, the secondary duct communicates with steam exiting the inner nozzles and the outer nozzles upstream of the mixing duct.

摘要： The present invention provides methods for pretreating water for desalination. According to one embodiment of the invention, a method for pretreating water is provided comprising simultaneously emitting acoustic energy to cause cavitation and light at a wavelength of 200 nm or less at the water. The light causes ozone to be generated. The ozone acts as an oxidizing and anti-foaming agent to sterilize the water. The ozone also inhibits the amalgamation of soft scales in the water. The inventors have also discovered that this method is more efficient than separately applying the acoustic energy and the light to the water. As a result, this method requires on average 25-30% less energy than separately applying the acoustic energy and light. The ozone is preferably removed or destroyed in the water after this method is performed. The ozone may be destroyed by emitting pulsed light at a wavelength of greater than about 200 nm at the water. Another embodiment of the invention is a method for pretreating water for desalination comprising emitting pulsed light at a wavelength of greater than about 200 nm at the water. Typically, the wavelength and intensity of the light is sufficient to destroy ozone in the water.

摘要： The present invention provides a heat exchange element for particular use in a film heat exchanger, such as a distillation system. The heat exchange element includes a substrate having a first surface and an opposing second surface. The first surface acts as a condenser surface. The heat exchange element further includes a composition disposed on at least a portion of the second surface. The composition has an exposed hydrophilic surface so as to provide a hydrophilic evaporator surface due to the composition being hydrophilic in nature. In contrast, the condenser surface is typically hydrophobic in nature. The use of the hydrophilic composition eliminates the nucleation of vapor bubbles and prevents gas film (or gas blanket) formation on the evaporator surface. As a result, the thermal resistance through the heat exchange element is decreased and the efficiency of the heat exchange element is increased.
