ABSTRACT:
A fluid filtration bag includes an outer porous fabric sleeve, and inner porous fabric liner, and a coherent filler material between the sleeve and liner. The filler material can act as the ancillary filtering media, while the sleeve and liner can act as containment mechanisms for the filler material. The liner has a pleated configuration, in which trough areas of the pleats are stitched to the fabric sleeve to form a series of tubes for containment and support of the filler material.
