Relating Water Permeability of Reverse Osmosis and Nanofiltration Membranes to the Polymer Density of their Active Layers
The water permeabilities of two polyamide thin-film composite membranes and polymerdensities of their active layers were measured. The results were analyzed under theframework of the free volume theory. Water permeabilities were measured using a dead end cell, and active layer densities were calculated by measuring the mass per unit area and avera...
