What is Nanofiltration?
Nanofiltration (NF), in concept and operation, is
much the same as reverse osmosis. The key difference is the degree of removal of
monovalent ions such as chlorides. Reverse osmosis removes the monovalent ions
at 98-99% level at 200 psi. Nanofiltration membranes’ removal of monovalent ions
varies between 50% to 90% depending on the material and manufacture of the
membrane. For this reason, there is a variety of Nanofiltration membranes
available. Each type is particularly suited to a certain application and may not
be acceptable to a different application.
Nanofiltration membranes (NF membranes) and systems are used for water softening, food and
pharmaceutical applications. For specifications and other information on
specific nanofiltration membrane (NF membrane) products,
