    Abstract: The present invention provides a polymeric, particularly aramid, fibrous nonwoven web having a relatively small pore size. The present inventive fibrous nonwoven web preferably has a high titer reduction with respect to bacteria such as Pseudomonas diminuta and viruses as exemplified by PR772 coliphage. The present invention further provides a method of filtering a fluid by passing a fluid through the present inventive fibrous nonwoven web, as well as a filter element incorporating the present inventive fibrous nonwoven web. The web may be coated to render it hydrophobic and oleophobic, and thus repellent to liquid chemicals. Such chemically repellent webs may be adapted for human apparel, and fashioned into garments suitable for use in adverse environments such as biological and toxic environments.

    Abstract: A method for filtering edible oils utilizing a backwashable filter assembly (10). A filter system having at least two filter assemblies (A, B) may be utilized to remove bleaching clay and/or nickel catalyst from oil being processed for human consumption. The filter assemblies may be connected in a tandem manner to provide continuous and uninterrupted filtering of the edible oil. Each filter assembly preferably comprises multiple, substantially cylindrical filter elements (18) having a porous filter medium which may be formed from polyaramid fibers. The filter elements are designed to withstand the elevated temperatures used in edible oil processing and for ease of cleaning during backwashing.
