Abstract

Official abstract text for this publication.

A desalination system, including a membrane distillation portion, a solar power concentration portion, and a thermal vapor compression portion operationally connected to the membrane distillation portion and to the solar power concentration portion. The membrane distillation portion includes a first vessel having a first portion and a second portion separated by a hydrophobic membrane operationally connected therebetween and oriented to pass water from the first portion to the second portion, wherein the hydrophobic membrane further comprises a hydrophilic membrane and an air blocking layer connected to the hydrophilic membrane and disposed in the first portion, a vacuum gap adjacent the hydrophobic membrane and disposed in the second portion, a first fluid inlet and a first fluid outlet operationally connected to the first portion, and a second fluid inlet and a second fluid outlet operationally connected to the second portion. The solar power concentration portion includes a pump having a pump outlet and a pump inlet operationally connected to a water line and to the vacuum gap, a linear Fresnel mirror collector for collecting and focusing sunlight, and an outlet line operationally connected to the pump outlet and positioned to receive focused sunlight from linear Fresnel mirror collector. The thermal vapor compression portion includes an ejector having an ejector inlet portion and an ejector outlet portion, wherein the ejector inlet portion is operationally connected to the outlet line and to the vacuum gap, a second vessel fluidically connected to the outlet portion and further including a heat exchanger operationally connected to the ejector outlet portion and to a water pipe, a feed spray operationally connected to the second outlet and positioned to spray into the heat exchanger, and a collection portion for receiving concentrated feed spray. The heat exchanger receives desalinated water from the ejector and from the feed spray. The water line carries desalinated water from the heat exchanger. The first outlet passes concentrated brine, and the first inlet receives feed water to be desalinated.
