Abstract: An integrated forward osmosis-membrane distillation (FO-MD) module and systems and methods incorporating the module is disclosed providing higher efficiencies and using less energy. The FO-MD module is osmotically and thermally isolated. The isolation can prevent mixing of FO draw solution/FO permeate and MD feed, and minimize dilution of FO draw solution and cooling of MD feed. The module provides MD feed solution and FO draw solution streams that flow in the same module but are separated by an isolation barrier. The osmotically and thermally isolated FO-MD integrated module, systems and methods offer higher driving forces of both FO and MD processes, higher recovery, and wider application than previously proposed hybrid FO-MD systems.

Abstract: Systems and methods using membrane distillation are provided for desalinating water, for example for the production of potable water, to address freshwater requirements. In an aspect the systems and methods do not require applying an external heat source, or the energy cost of the heating source, to heat the feed stream to the membrane. In an aspect, the sensible heat present in surface seawater is used for the heat energy for the warm stream fed to the membrane, and deep seawater is used as the cold/coolant feed to the membrane to provide the needed temperature gradient or differential across the membrane.

Abstract: A membrane distillation module includes a housing having a hot inlet for receiving a hot feed and a hot outlet for expelling the hot feed; a porous membrane located inside the housing and having an outside surface that defines an enclosure, the outside surface being configured to contact the hot feed, wherein the porous membrane is configured to prevent the hot feed from passing from outside the porous membrane to an inside of the enclosure; and a non-porous conduit located inside the enclosure, the non-porous conduit having an inlet for receiving a cold feed and an outlet for expelling the cold feed.

Abstract: A multi-stage flash reversal unit includes a housing; plural stages located inside the housing; an evaporation port that receives a water feed having a first temperature; a condensation port that outputs a concentrated water feed having a second temperature, which is lower than the first temperature; and a cooling unit that cools down the concentrated water feed.
