摘要:
Provided are filter elements and methods of making and using the same where the filter elements are suitable for liquid filtration and contain particle-loaded meltblown fiber webs. A filter element comprises: a porous article comprising a web of self-supporting nonwoven polymeric fibers and a plurality of sorbent particles enmeshed in the web, the article comprising a first surface and a second surface; a liquid-impermeable housing surrounding the porous article; an inlet in fluid communication with the first surface; and an outlet in fluid communication with the second surface. Spiral-wound webs, web-covered blocks, and stacked disks of webs are also provided.
