Thin Film Composite (TFC) - A thin film composite or TFC is a reverse osmosis membrane composed of and manufactured as three layers bonded together. The two base layers of the asymmetric design have a thin skin (3rd) layer of either polyamide or charged polysulfone deposited on the surface. The thin film is the salt rejecting layer where the two base layers provide a porous structure whose primary function is strength.
