Start Date: 7/01/16

End Date: 6/30/17

Abstract

An ideal filter media should exhibit high filtration efficiency at low pressure drop and have long filter life (i.e. high dust holding capacity). Challenges in the filter media engineering is to achieve these three contradicting goals. Then, controlling and engineering various aspects of filter media structures poses critical importance to achieve high filtration performance. Therefore, understanding of 3D structure of filter media and changes in these structures during the filter use is essential to engineer ideal filter media. In this proposed research I aim to analyze 2D & 3D structures of filter media and evaluate their impacts on filtration properties. X-ray micro computed tomography (micro-CT) will be used to visualize inner structure of filter media and imaging analysis technique will be developed to quantify 3Dstructural characteristics of filter media. Then, the role of filter structures in filtration properties will be investigated. In particular, I am interested in the loading of the particle during the filter use and impacts of filter structures on filtration properties during the particle loading.

Start Date: 11/01/13

End Date: 9/30/14

Abstract

The goal of this proposed research is to develop techniques to evaluate the degree of entanglement/dispersion of short-cut fibers dispersed in the aqueous media. More specifically, we purpose to develop image analysis technique to qualitatively and quantitatively evaluate fiber dispersion and entanglement in the aqueous media. This will include establishing a protocol of sample collections, optimization of image capture conditions and development of proper image analysis algorithms as schematically shown in Figure 1. We plan to create a set of fiber/media dispersions with different degree of dispersion and entanglement by adjusting fiber length/diameter ratio, fiber concentration and dispersion time to use as a reference set. The purpose of this is to check effectiveness and applicability of technique to be developed through procedure. Fiber samples will be collected from this reference set and dispersion defect will be visualized (Task 1). The result of task 1 would be used to qualitatively evaluate the degree of fiber entanglement. In next step, we pursue to develop image analysis technique to provide further information and more quantitative analysis. Two different methodology would be used – separation/detection of fiber bundles (Task 2) and application of uniformity analysis (Task 3). In the end of the project period, fiber/particle mixture may be introduced to see feasibility of fiber/particle dispersion analysis using the proposed the scheme.
