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 …
The outlook for nonwoven filter media
These drivers and developments have resulted in the nonwoven filtration market consuming an ever-greater amount of nonwoven material, reaching 1.3 million tonnes in 2018, an annual increase of 7.5% from 2008. The filtration end use is the fifth largest (in tonnage) of the nonwoven segments, consuming 9% of the world’s nonwovens production in 2018, and …
Spiral-wound cartridges for desalination
A spiral-wound element has significant surface area, resulting in extremely high packing density. The filter is also easy to install and maintain in the system, and it offers a long life due to the durability of the spiral-wound element. The history of desalination dates back to Aristotle and other intellectuals in ancient Greece. In the …
Student Spotlight: Electrospun nanofibers for filtration
