Abstract
In this paper, we apply the Hagan-Poiseuille Model and the resistance model to perform an original analysis of previous experimental studies of water transport through polycrystalline Linde Type A (LTA) zeolite membranes and nanocomposite polymer/LTA membranes. From our analysis we estimate the intrinsic water permeability of LTA zeolites and the zeolite/polymer interface. We find that the permeability of a single LTA crystal is significantly greater than the intrinsic permeability of a commercial seawater reverse osmosis membrane or a commercial cellulose-acetate forward osmosis membrane.
