    摘要: In a header (17), or potting head, of a membrane module, each of a plurality of hollow fiber membranes (10) has at least one open end (12) collected together into a group wherein the membranes are surrounded by a solidified adhesive (100) near the ends of the membranes, the open ends of the membranes extend beyond a first side of the solidified adhesive, and a bond between the solidified adhesive and the membranes is less strong than all of the materials in the membrane and any and all bonds between materials in the membranes. A solidified fixing liquid (14) around the membranes extends from the solidified adhesive (100) to a point at or near the ends (12) of the membranes. The solidified fixing liquid (14) : surrounds each membrane (10) for at least a portion of its length in the solidified fixing liquid between the solidified adhesive (100) and the end (12) of each membrane; sealingly connects to the outside of each membrane; does not block the open ends (12) of the membranes; and does not contact the membranes on a second side of the solidified adhesive. A header pan (18) is secured to the solidified fixing liquid (14) in a position where the open ends (12) of the membranes (10) are in fluid communication with a permeate channel in the header pan. The solidified fixing liquid (14) extends to and is secured directly in the header pan (18) and separates the solidified adhesive (100) from the header pan (18).

    摘要: To pot membranes in a header, a dense, viscous liquid, suspension or, preferably, a thixotropic, water soluble gel, is placed in a header pan in space reserved for a permeate channel. A plurality of hollow fibre membranes are collected together and their open ends are inserted into the gel. A fixing liquid, typically a resin, is placed over the gel. The fixing liquid surrounds each membrane and then solidifies, simultaneously sealing the outer surfaces of the membranes and forming a plug in the opening of the header to complete the permeate channel. After the fixing liquid has solidified, the gel is removed by various means. The space initially occupied by the gel becomes part of the permeate channel after the gel is removed. In one embodiment, membranes are grouped by a cushioning adhesive which later surrounds the membranes where they exit the completed header.
