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.

Membrane distillation module and multi-effect process

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.

A periodic mesoporous organosilica (PMO) nanoparticle functionalized nanocomposite membrane (NCM) for membrane distillation, the NCM including: polymer fibers such as polyetherimide fibers aggregated into a matrix; and hydrophobic PMO nanoparticles disposed on the polymer fibers. The PMO nanoparticles include a framework connected by organic groups and pentafluorophenyl groups. Good membrane flux and anti-fouling was demonstrated. Membranes can be prepared by electrospinning.

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.
