Nanofiltration Membranes are thin film composite membranes. They have the unique characteristic of rejecting, or defractionation of divalent ions such as Nickel, Copper, Chrome & Cobalt. Nanofiltration Membranes are used on lower system operating pressures because they have very high membrane flux (permeate flow per unit of membrane area).
A unique characteristic of the Nanofiltration family of thin film composite membranes, is its resistance to fouling. Particularly in acid streams, the membrane requires minimal down time for cleaning. The low molecular weight cut off range of 200-300 makes nanofiltration extremely effective in removing contaminants from Acids & Bases that enable reuse of the commodity.
