摘要： A membrane distillation system includes a distillation vessel, an array of hollow fiber membranes pervious to distillate vapor but impervious to feed solution and an array of hollow tubes impervious to distillate vapor and feed solution but which allow thermal energy transmission. The system further includes a pump, a heat exchanger for heating the feed solution before it enters the hollow fiber membranes, and an outlet for removing distillate from the distillation vessel. A method for removing distillate from a feed solution includes delivering the feed solution through hollow tubes spanning a distillation vessel, heating the feed solution, delivering the feed solution through hollow fiber membranes spanning the distillation vessel to create a vapor pressure differential between the hollow fiber membranes and a distillation volume within the distillation vessel, and removing distillate from the distillation vessel.

摘要： A membrane distillation system includes a membrane distillation module, a brine loop and a distillate loop. The brine loop and the distillate loop each include means for regulating flow of brine solution and distillate, respectively, to the membrane distillation module. The flow of brine solution and distillate is regulated to prevent brine solution and distillate from penetrating membranes of the membrane distillation module. A method of membrane distillation includes delivering brine solution and distillate to the membrane distillation module at low pressures in a first mode. The method also includes heating the brine solution and cooling the distillate and delivering portions of each to the membrane distillation module in a second mode. The portions of heated brine solution and cooled distillate are adjusted to facilitate membrane distillation while preventing liquid from penetrating membranes of the membrane distillation module.

摘要： A treatment system includes a feed source, a first treatment unit for separating a feed into a first product and a concentrated feed containing less than about 7% total dissolved solids, and a membrane distillation unit for separating the concentrated feed into a second product and a superconcentrated feed containing at least about 14% total dissolved solids. The membrane distillation unit includes hollow fiber membranes having inner bores for receiving the concentrated feed and membrane walls for allowing vapor transmission of distillate. A method includes delivering feed to a first treatment unit where it is separated into first product and concentrated feed streams; delivering the concentrated feed to internal bores of hollow fiber membranes where it is separated into second product and superconcentrated feed streams as vapor passes across the hollow fiber membranes; delivering the superconcentrated feed to a liquid removal unit; and collecting the first and second product streams.
