Industrial NF Membrane
Industrial NF Membrane
AMFOR® NF membrane element are designed for process applications where a separation of solutes is desired. NF membrane is a durable membrane designed to reject organics with a molecular weight above 200 while passing monovalent salts, we also can produce sanitary NF Element.
