Nanofiltration Membranes

Covering fabrication, characterization, and applications nanofiltration (NF) membranes, this book provides a comprehensive overview of the development of NF membrane technology over the past decade. It uniquely covers a variety of fabrication techniques, comparing the procedures of each technique to produce polymeric membranes of different morphologies. The book also discusses advances in the materials used in thin film composite (TFC) polyamide membrane fabrication and their influences on properties with respect to structural and separation characteristics. A comprehensive review on NF characterization methods and techniques is provided, assessing physical and chemical properties and separation characteristics and stability. Technical challenges in fabricating a new generation of NF membranes are also reviewed and the possible approaches to overcome the challenges are provided. The book concludes with relevant case studies on the use of NF membranes in industrial implementation of both aqueous and nonaqueous media.
