Abstract
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 operational…
