Effect of Nanofiber Diameter on Filtration Efficiency
Advanced Materials Research, 2012Electrospinning and its application in filtration area have been caught much attention because of the large surface-to-volume ratio of nanoweb , which affects the filtration efficiency by possibly giving more particle-capture sites. In this study, PAN is electrospun to produce ultra-fine nonwovens, and its characteristics as filter media are investigated.

Respirator Filtration Efficiency Testing
1986The existing methods for evaluating particulate respirator filters as found in 30 CFR Part 11 are presented. Shortcomings with these methods are discussed in detail. NIOSH's research objectives for updating particulate respirator filter testing are presented along with some research findings. Conclusions are drawn from these results and areas of future

Effect of Flocculation on Gypsum Filtration Efficiency
1991Improvement in filtration efficiency of gypsum upon flocculation is determined to be due to reduction in the blockage of filter media pores and in the filter cake resistance. An optimum in polymer dosage is explained in terms of stabilization of fines and deformability of the flocs formed.
