摘要： A multi-effect membrane distillation system includes first and second membrane distillation effects. Each effect (stage) includes a feed channel, a gap, and a vapor-permeable membrane separating the feed channel from the gap. A liquid feed is fed into the feed channel of the first effect via a feed inlet, and the liquid feed is extracted from the firt-stage feed channel ia a first feed-transfer conduit that delivers the liquid feed to the second-stage feed channel. The feed is extracted from the second-stage feed channel via a second feed-transfer conduit. At least one permeate-extraction conduit is coupled with the first-stage and second-stage gaps and is configured to extract permeate (e.g., pure water) therefrom.

摘要： A feed of at least one of (a) a source liquid including a solvent with a dissolved impurity and (b) a retentate of the source liquid is pumped in a substantially closed loop through a liquid-separation module. The liquid-separation module includes a membrane that passes at least partially purified solvent to a permeate side of the membrane while diverting the impurity in a retentate on the retentate side of the membrane. The purified solvent is extracted from the permeate side of the membrane; and the retentate from the liquid-separation module is pumped to or through a pressurized reservoir with a variable volume for the feed component and recirculated as a component of the feed. Over time, the volume for the feed is reduced and the pressure applied to the feed in the reservoir is increased to balance against an increasing difference in osmotic pressure across the membrane.

摘要： A humidification-dehumidification apparatus featuring enhanced heat recovery includes a shared interior wall extending along a vertical axis and defining and separating humidifying and dehumidifying chambers. Heat-transfer members extend through the shared interior wall and across a majority of each chamber, while a spray device is configured to direct a spray of liquid feed composition onto the heat-transfer members inside the humidifying chamber. The liquid feed collects on the heat-transfer members in the humidifying chamber, and water evaporates from the liquid feed on the heat-transfer members, leaving a concentrated remainder of the liquid feed in liquid form. Carrier gas passes through the humidifying chamber where evaporated water is entrained in the carrier gas to form a moist carrier gas that passes from the humidifying chamber to the dehumidifying chamber, where the water vapor condenses from the moist carrier gas on the heat-transfer members.

摘要： An aqueous solution flows through a desalination system that separates the aqueous solution into purified water and concentrated brine. The concentrated brine is directed into an electrodialysis system that includes an anode and a cathode and at least two monovalent selective ion exchange membranes between the anode and the cathode. At least one of the monovalent selective ion exchange membranes separates at least one diluate channel from at least one concentrate channel in the electrodialysis system, and this membrane selectively allows at least one monovalent ion to pass through the membrane while blocking or inhibiting the transport therethrough of multi-valent ions. The concentrated brine flows through at least the concentrate channel while a voltage is applied to the anode and cathode; and additional aqueous solution flows through the diluate channel.

摘要： A carrier-gas mixture is directed through a fluid flow path (16, 18) in a combined heat and mass transfer device (12, 14), which can be operated at sub-atmospheric pressure. Heat and mass are transferred from/ to the carrier-gas mixture via interaction with a liquid composition including a vaporizable component in a liquid state to substantially change the content of the vaporizable component in the carrier-gas mixture via evaporation or condensation. The mass flow rate of the carrier-gas mixture is varied by extracting/injecting (60, 62, 64) the carrier-gas mixture from at least one intermediate location in the fluid flow path, and/or the mass flow rate of the liquid composition is varied by extracting/injecting the liquid composition from at least one intermediate location in the fluid flow path. The flow of the carrier-gas mixture or the liquid composition is regulated to reduce the average local enthalpy pinch.

摘要： In a bubble-column vapor mixture condenser, a fluid source supplies a carrier-gas stream including a condensable fluid in vapor phase. The condensable fluid in liquid form is contained as a bath in a chamber in each stage of the condenser, and the carrier gas is bubbled through the bath to condense the fluid into the bath. Energy from condensation is recovered to a coolant in a conduit that passes through the liquid in the stages of the condenser. The bubble-column vapor mixture condenser can be used, e.g., in a humidification-dehumidification system for purifying a liquid, such as water.
