Impact of the Filter Roughness on the Filtration Efficiency for Aluminum Melt Filtration
2019Melt cleanliness is essential for high quality aluminum production. The main cleanliness criteria are the content of dissolved hydrogen as well as the content of non-metallic inclusions. The latter may impair the castability of the aluminum melt as well as the mechanical properties and the machinability of the aluminum castings.

Advanced Compact Filtration (ACF): An Efficient and Flexible Filtration Process
2016Deep bed filters are well known not only for providing efficient inclusion removal that is required for critical products, but also for their relatively high metal hold-up. In multi-alloy casthouses, filtration costs associated with deep bed filters can be considerable due to filter media replacement and scrap metal generation at alloy changes.

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.
