Criteria for Selection of Pore Structure Characterization Techniques for Filtration Media

摘要

Selection of suitable pore structure characterization technique is essential to measure relevant pore structure of desired media. The technique selected out of the many available should measure through pore throat diameter, distribution, permeability and volume while the filtration media are stable. Table 1 summarizes the strengths and limitations of the techniques (Figure 1) [1]. Complete inter cartridges can be tested in complete filter cartridge tester which overcomes problems due to high flow, high correction factor, and variable cartridge size (Figure 2). For accurate, reproducible and objective results obtained under controlled experimental conditions, the automated Advanced Capillary Flow Porometers is used (Figure 3). Tests can be performed under a range of application environments like compres-sive stress, temperature, and humidity.
