Evaluation of Filtration Performance for Depth Filter Media using Different Standard Test Dusts
Initial filtration performance and loading characteristics are the main parameters of the depth filter media. These parameters give an overview of the filtration performance based on which the future specification of the depth filter media is made. Initial filtration performance as well as the characterization of the filter media structure is made using the flat sheet media. The dust loading characteristics of the depth filter media are evaluated using the assembly as a filter cartridge made of the same depth filter media as flat sheet media. During this study we have used the samples of the depth filter media TFM2 and the test apparatuses designed in our laboratory to meet some of the standard test procedures. Test particles used during these tests include the test with KCl particles and A2 fine as a standard test dust and NaCl in our previous tests. The results from the conducted tests indicate a low pressure drop due to multilayer structure and a high particle collection efficiency which is mainly attributed to the final layer consisting of meltblown fibers of small diameters and dense packing structure.
