Abstract
An assembly of hollow fibers for use in fluid treatment apparatus and apparatus incorporating such assemblies, in which a primary frame is provided with a central window defined by edges at least two of the opposite edges being thinned down to form hollows. A web of hollow fibers is placed in the hollows and is secured in place, and the fibers secured to one another, by a mass of hardened resin material in at least one of the hollows. The assemblies are mounted in a container, through which a first fluid is caused to flow, the fluid passing around the fibers and through the windows before leaving the container. The interiors of the hollow fibers are connected to the exterior of the container so that either fluid permeate flows out of the apparatus via the interiors of the fibers or a second fluid is caused to flow through the interiors of the fibers if some form of fluid exchange is desired.
