Abstract
A microfiltration filter, an assembly containing such a filter and a method of manufacturing such a filter is provided. In one embodiment the method comprises folding a sheet of woven fibre filtration material onto itself, thereby providing an elongate double sheet of filtration material having two substantially parallel planar sides with aligned edges. The double sheet has open and bind long edges and two short opposing open edges. The method includes positioning an elongate collection manifold between the sides at least partway along and at or near the blind edge, providing a fluid outlet in at least one of the sides wherein the fluid includes sealing the open long edge and short edges of the double sheet to form a liquid impervious seal and a planar, elongate collection chamber between the sides, and folding the elongate collection chamber across the long edges to create a filter with multiple adjacent layers of planar, elongate collection chamber.
