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. …
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 …
