Abstract

In this study, we analyzed prefilter media and compared an original nonwoven filter and the media after postprocessing. Low melt fibers (LMFs) and polyphenylene sulfide fibers possessing chemical- and heat-resistant properties were used to develop the prefilter media. We analyzed the physical properties of the filter media and its performance, such as initial fractional efficiency, dust-retaining capacity, and arrestance. In particular, we investigated the effect of the post-drying process on the performance of the filter. Although there was no significant improvement in the filter performance, it is expected that bonding using LMFs or resin will enhance the physical properties of the filters to a greater extent than needle-punching processing where the fibers are mechanically bonded. The physical properties of the filter subjected to the post-drying process, such as tensile load and tear strength, were higher than those of the dough. Although filter media subjected to the post-drying process are less efficient, they are more durable and can be used for a long time. It is expected that including a post-drying process can reduce the energy consumption of the entire filtration system.
