Claim:
1. A method of potting hollow fiber membranes, comprising the steps of: forming a bundle of hollow fiber membranes with a first layer of adhesive material spaced from an end of the bundle; providing a plate around the bundle, the plate extending from and compressing the first layer of adhesive material; covering the end of the bundle with a permeate pan to define a permeate collection space between the permeate pan and the first layer of adhesive material, the permeate pan abutting the plate, the end of the bundle within the permeate collection space; flowing a liquid potting material into the permeate collection space to form a layer of liquid potting material in contact with the permeate pan and the bundle, the layer of liquid potting material extending from the first layer of adhesive material to a level at or below the end of the bundle; and allowing the liquid potting material to harden to bond the permeate pan to the bundle of hollow fiber membranes, wherein the bundle of hollow fiber membranes is formed with a second layer of adhesive material between the first layer of adhesive material and the end of the bundle, and wherein the liquid potting material is flowed into the permeate collection space to form a layer of potting material that extends only as far as the second layer of adhesive material.
