Technical Note By Dr. Dhawan:

What is Nanofiltration?

Nanofiltration, 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 and systems are used for water softening, food and pharmaceutical applications. For specifications and other information on specific nanofiltration membrane products, visit http://www.appliedmembranes.com/mem.html

Design Tip: Like RO Membranes, Nanofiltration Membranes require pretreatment to protect against scaling and fouling.
