Polyamide Membranes - Polyamide membranes were first Introduced during the early 1970’s. Asymmetric polymer is used in the construction of thin film composite (TFC) spiral wound membranes.

Polyamide membranes are the most commonly used membrane construction materials because of their lower pressure requirements and more flexible operating conditions. Polyamide membranes are oxidant (chlorine, chloramine, bromine, ozone etc.) intolerant. It is also noteworthy that the surface of the polyamide membrane carries an anionic charge, this makes it slightly more susceptible to fouling from contaminants carrying a cationic charge.
