Hollow fiber assembly for use in fluid treatment apparatus
First Claim
1. A hollow fibre assembly for use in fluid treatment apparatus, said assembly comprising, in combination:
- a. a primary frame having edges defining a central window;
b. a thinned down portion of at least two of said edges defining at least two hollows;
c. a mass of resin material in at least one of said hollows;
d. a web of hollow fibres extending between said hollows, with the ends of the hollow fibres embedded in said mass of resin material, open ends of said hollow fibres opening on a face of the mass.

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.

13. A hollow fibre assembly for use in fluid treatment apparatus, said assembly comprising a plurality of frames fixed to one another, each said frame comprising, in combination:
-
a. a primary frame having edges defining a central window; b. a thinned down portion of at least one of said edges defining at least two hollows; c. a mass resin material in at least one of said hollows; d. a web of hollow fibres extending between said hollows with the ends of the hollow fibres embedded in said mass of resin material, open ends of said hollow fibres opening in a face of the mass. - View Dependent Claims (14, 15, 16, 17)

18. Fluid treatment apparatus comprising a container, a stack of hollow fibre assemblies located in said container each said assembly comprising, in combination:
-
a. a primary frame having edges defining a central window; b. a thinned down portion of at least two of said edges defining at least two hollows; c. a mass of resin material in at least one of said hollows; d. a web of hollow fibres extending between said hollows, with the ends of the hollow fibres embedded in said mass of resin material, open ends of said hollow fibres opening on a face of the mass; said assemblies being arranged in said container whereby said container is in fluidtight engagement with the frames thereof, means for feeding a first fluid to said container so that it flows around said fibres and through the windows before leaving the container and means for connecting the interior of the hollow fibres to the exterior of the container. - View Dependent Claims (19)
