Book Description :

This study is aimed at developing modeling methodologies for simulating the flow of air and aerosol particles through fibrous filter media made up of micro- or nano-fibers. The study also deals with modeling particle deposition (due to Brownian diffusion, interception, and inertial impaction) and particle cake formation, on or inside fibrous filters. By computing the air flow field and the trajectory of airborne particles in 3-D virtual geometries that resemble the internal microstructure of fibrous filter media, pressure drop and collection efficiency of micro- or nano-fiber filters are simulated and compared with the available experimental studies. It was demonstrated that the simulations conducted in 3-D disordered fibrous domains, unlike previously reported 2-D cell-model simulations, do not need any empirical correction factors to closely predict experimental observations. This study also reports on the importance of fibers' cross-sectional shape for filters operating in slip (nano-fiber filters) and no-slip (micro-fiber filters) flow regimes. In particular, it was found that the more streamlined the fiber geometry, the lower the fiber drag caused by a nanofiber relative to that generated by its micron-sized counterpart. This work also presents a methodology for simulating pressure drop and collection efficiency of a filter medium during instantaneous particle loading using the Fluent CFD code, enhanced by using a series of in-house subroutines. These subroutines are developed to allow one to track particles of different sizes, and simulate the formation of 2-D and 3-D dendrite particle deposits in the presence of aerodynamic slip on the surface of the fibers. The deposition of particles on a fiber and the previously deposited particles is made possible by developing additional subroutines, which mark the cells located at the deposition sites and modify their properties to so that they resemble solid or porous particles. Our unsteady-state simulations, in qualitative agreement with the experimental observations reported in the literature, predict the rate of increase of pressure drop and collection efficiency of a filter medium as a function of the mass of the loaded particles.

Book Description :

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.

Book Description :

Separation of liquid-liquid dispersions is important industrially and environmentally. Fibrous coalescing filters are used to separate liquid-liquid dispersions. Wettability of the fibers significantly influences the filter performance. The wettability of the filter media depends on surface properties of fiber materials and porosity of the filter medium. The wettability of filter media and interfacial tension of the liquid are the important factors in designing a coalescing filter media. It is generally accepted that the intermediate wettability gives best filter performance. However, the effect of wettability on filter performance is not well understood, especially at low interfacial tension liquids. In addition, wettability characterization techniques are not widely applied for fibrous filter media. The goal of this work is to study the effect of wettability on filter performance and by evaluating filter media of varying wetting properties. In this work, filter media were prepared by mixing hydrophilic and hydrophobic fibers to control the wettability and to improve the performance of the filter media. The mixing of fibers was achieved by designing filter media in different geometries. The different geometries developed and evaluated are mixed, layered and radially layered hydrophilic/hydrophobic fiber media. The wettability of the filter media was characterized using modified Washburn's equation and expressed as the Lipophilic to Hydrophilic (L/H) ratio. Water and Viscor-1487 oil were used as test liquids for the wettability characterization. The developed geometries resulted in variation in wettability. The filter media were tested in liquid-liquid coalescence experiments in which fine emulsion was generated by dispersing water droplets in the Viscor-1487 oil. The experimental results show that wettability of filter media can be controlled by constructing a media with different geometries and choosing a right composition of hydrophilic/hydrophobic fibers. The pressure drop of filter media was reduced with increase in L/H. The performance of filter hydrophilic/hydrophobic filter media was improved as compare to only glass fiber (hydrophilic) media. However, improvement in quality factor is mainly due to reduction in pressure drop. The best filter performance was achieved with layered and radially layered structures made of glass and polypropylene fibers having L/H between 2 to 10. The media developed with glass and electrospun polypropylene fibers shows significant improvement in separation efficiency but also increase in pressure drop. The results and approach of this work will be useful in designing and developing filter media for many industrial filtration applications.

Book Description :

Nonwoven fibrous media with nanofibers have significant filtration applications in automotive, chemical, transportation, power generation and pharmaceutical/biological industries. Nanofibers have higher capture efficiencies in comparison to microfibers in the submicron particle size range of 100 - 500 nm because of smaller fiber diameter and increased surface area of the fibers. Nanofibers are in the slip flow regime as a consequence of which steep increase in pressure drop is considerably reduced due to slip effect. The economic benefits of using nanofiber filter media are improved filter performance and compact filters. Electrospinning process was used to fabricate polymer and ceramic nanofibers. The electrospun polymer nanofibers were added to the nonwoven fibrous media to improve filter performance for air filtration. This improved filter performance was in consistent with numerical modeling. This book describes the experimental and modeling results of particle loading on fibrous media and application of ceramic nanofibers for hot gas filtration applications.

Book Description :

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
