Handbook of Nonwoven Filter Media

The Handbook of Nonwoven Filter Media, Second Edition provides readers with a fundamental understanding of nonwoven filter media. It is one of the few books dealing exclusively with the subject, and is primarily intended as a reference for people in the nonwovens industry (industry and academic researchers, technical, marketing , and quality control personnel) and universities offering courses in filtration theory and practice and nonwovens technology.

The book includes applications for  gas, liquid, and engine filtration, and identifies  the types of filter media used in these applications. The various separation technologies that can be achieved with  nonwoven filter media are revealed and discussed. Theoretical presentation is based on flow through porous media, and is developed around a nonwovens or engineered fabrics orientation.

• Presents the latest  information on legislative, regulatory, environmental and sustainability issues affecting the nonwovens and filtration industries
• Includes a comprehensive discussion of Computational Flow Dynamics (CFD) by Dr. George Chase, University of Akron, USA
• Includes the latest Global and North American marketing statistics for filters and filter media prepared by Brad Kalil of INDA.
