How fiber diameter & size affect filtration performance
There are three primary property considerations of fibers for filtration performance — the choice of fibers, the process of producing the media and the final application. When it comes to performance, the fundamental fiber properties are those that are designed to optimize volume, air permeability, and the pore size of the material. …
Mann+Hummel’s Filter Cube poised to go global
A successful air pollution reduction scheme instigated by filtration specialist Mann+Hummel in Germany is set to be replicated at “hot-spots” around the world. As the home of both Mercedes and Porsche, Stuttgart owes its status as Germany’s richest city to the automotive industry, but in January 2019, a first partial car ban was imposed, effectively …
Student Spotlight: Droplet mobility on nonwoven surfaces
Mohammad Jamali is pursuing a Ph.D. in Mechanical Engineering at Virginia Commonwealth University, where he is conducting research on understanding droplet mobility and penetration in nonwovens via numerical simulation and complementary experiments at the Porous Media and Multi-Phase Flows (PMMF) Laboratory. His project is supported by The Nonwoven Institute at North Carolina State University. After …
Are we on the verge of a stormwater catastrophe?
Why should we care about stormwater? Have you ever wondered what a mass extinction event might look like? Certainly, such events are well documented in the geologic record, involving gamma ray bursts, asteroids and comets, and perhaps the biggest killer so far, volcanism. Volcanism is commonly accepted as the cause of the Permian-Triassic extinction, also known as …
FILTECH 2019: The media is the message …
Despite the vast scale, complexity and diversity of today’s filtration system installations, the simple filter media is the key to everything. Or the not so simple filter media, as became evident when assessing just a handful of the over 200 presentations running parallel to this year’s FILTECH exhibition, which took place in Cologne, Germany, from …
