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...

This paper describes research of incorporation 2-aminoimidazoles (2-A1) a anti-biofilm molecule into the NF/RO membrane matrix for fouling control. The specific objectives of this research were to: (1) determine whether a 2-AI would be amenable to incorporation into water purification membranes and maintain anti-biofilm activity once incorporated...
