Abstract:
1. A system for desalination of brine, comprising: a module that includes a membrane formed by a plurality of porous hydrophobic hollow fibers, each of the plurality of porous hydrophobic hollow fibers defining an internal and an external surface and including a hydrophobic porous coating on at least one of said internal surface and said external surface, wherein the hydrophobic porous coating exhibits a pore size of at least 30 Å; wherein the hydrophobic porous coating is effective to prevent salt intrusion and pore wetting of the porous hydrophobic hollow fibers, and wherein each of the plurality of coated hollow fibers is characterized by a wall thickness and an inner diameter effective to establish a steady state water vapor permeation flux of at least 20 kg/m
