Nanofiltration (NF) is a new type of pressure driven membrane process and used between reverse osmosis and ultrafiltration membranes. The most different speciality of NF membranes is the higher rejection of multivalent ions than monovalent ions. NF membranes are used in softening water, brackish water treatment, industrial wastewater treatment and reuse, product separation in the industry, salt recovery and recently desalination as two pass NF system. In this chapter, a general overview of nanofiltration membranes, membrane materials and manufacturing techniques, principles such as performance and modelling, module types, membrane characterization and applications on water and wastewater treatment were given read more ...
