Abstract
A method of sealingly coupling a hollow fiber bundle having first and seconds ends to a porous collar having first and second peripheral edges, at least one of which is coupled to the inner ledge of a casing for encasing said bundle of hollow fibers is disclosed. The method broadly includes providing a porous collar having first and second outer peripheral edges; providing a casing having first and second longitudinal ends, the casing defining a central chamber, the chamber having first and second open ends wherein the longitudinal ends of the casing each include an inner lip proximal to the open end; coupling the first outer peripheral edge of the porous collar to the inner lip of the casing; retaining a bundle of hollow fibers having first and second longitudinal ends within the chamber; permeating the longitudinal ends of the hollow fiber bundle with a fluid impermeable material; joining the porous collar to the fluid impermeable material by penetration of the material into the porous collar; and curing the fluid impermeable material. The method provides a fluid impermeable seal between the casing and the individual hollow fibers. The seal prevents the unfiltered fluid from comi…
