Polyamide - RO MembranesAdvanced Reverse Osmosis TechnologyPolyamide Membranes - Introduced in the early 1970’s this asymmetric polymer is used in the construction of thin film composite (TFC) spiral wound membrane. Polyamide membranes are the most typical membrane construction material due to less pressure requirements and more flexible operating conditions. Polyamide membranes are oxidant (chlorine, chloramine, bromine, ozone etc.) intolerant. Also noteworthy is that surface of the polyamide membrane carries an anionic charge that makes it slightly more susceptible to fouling from contaminants carrying a cationic charge.
