Aerosol Filtration

Filtration of aerosols is omnipresent in our daily lives, in areas as diverse as health, the protection of people and the environment, and air treatment inside buildings. However, the collection of particles within a filter media is not, contrary to popular belief, linked to a simple screen effect. The phenomena involved are much more complex and require the consideration of aerosol interactions, filter media and process conditions to select the best fiber filter for a given application. Aerosol Filtration, book for students, hygiene or process engineers, fibrous media manufacturers, designers, and filtration system suppliers or users addresses the filtration of aerosols in six chapters. These chapters cover physics and aerosol characterization, the fibrous media, and efficiency and filter clogging by solid or liquid aerosols, with special attention to the filtration of the nanoparticles.

• Analyses the behavior of fibrous media against solid and liquid aerosols
• Presents models of efficiency and pressure drop
• Introduces computing elements for estimating the lifetime of filters
• Provides guidance for designing filters and predicting their behavior over time

Auteur

Professor of Process Engineering at the University of Lorraine. His research is in aerosol filtration, a subject he introduced to the laboratory in 1994 (The Laboratory Reactions and Process Engineering (UMR CNRS 7274)). His research focuses on the separation of liquid and / or solid (nano to micron dimensions) with filter media or other methods of separation and characterization of aerosols. His research interests include: areas of personal safety (respirators, safety filters), the environment (atmospheric particulate emissions) and methods (protection filter). He is board member of the ASFERA (French Association for Studies and Research on Aerosols), founding member and vice president of the French Society of Fluid Separations-Particles (SF2P).
