A prefilter bag for insertion into a standard filtration bag apparatus, having a filtration assembly comprising a seamless filter membrane having uniform pore openings preselected within the range of between about 2 and about 50 microns (. mu. ) and a linearly channeled, non-deformable, semi-rigid liquid transport thermoplastic sheet in the form of a molded webbing or netting in contact with the upper surface of the filter membrane; said webbing having marginal edges which are coextensive with those of the membrane; said assembly adapted to be shaped by continuous winding of the assembly upon itself for 2 to 5 complete convolutions around a tubular mandrel so as to form a cylindrical tube or cone; the bottom of said cylinder being sealed to prevent liquid leakage and the top of said cylinder, forming a liquid inlet opening, being sealed to a retaining ring adapted to be inserted in, attached to or sealed to an outer, retaining ring of a non-wrapped filter bag. The inlet of the wrapped cylindrical bag is optionally fitted with vortex directing means to enhance a linearly tangential direction of the entering liquid against the walls of the inside membrane. The invention also pertains to a method for the fabrication and use of the present filtration bag.
