Method of potting hollow fiber membranes
First Claim
1. A method of potting a plurality of hollow fiber membranes into a mass of solidified potting liquid comprising the steps of, a) providing a plurality of hollow fiber membranes, the membranes having terminal portions adjacent open ends;
- b) enclosing the open ends and terminal portions of the hollow fiber membranes in a first material held in a container;
c) flowing a potting liquid in the container over the first material, which potting liquid surrounds each hollow membrane and then becomes a solid mass which provides a fluid-tight seal to the outside of the hollow fiber membranes, the first material preventing the potting liquid or solid mass from closing said ends of the membranes; and
, d) removing the first material from said ends and terminal portions of the hollow fiber membranes.

Abstract
A method of potting a plurality of hollow fiber membranes into a mass of solidified potting liquid is described. Open ends of a plurality of hollow fiber membranes are enclosed in a first material held in a container which may be a part of a permeate collection means, for example, a permeate pan or header enclosure. A potting liquid is flowed into the container over the first material. The potting liquid surrounds each hollow fiber membrane and then becomes a solid mass that provides a fluid-tight seal to the outside of the hollow fiber membranes. The first material prevents the potting liquid or solid mass from closing the ends of the membranes. The first material is later removed from the ends of the hollow fiber membranes.

15. A method of potting a plurality of hollow fiber membranes into a mass of solidified potting liquid fixed to a permeate pan or other header enclosure of a filtration module comprising the steps of,
a) providing a plurality of hollow fiber membranes, the membranes having terminal portions adjacent open ends; -
b) enclosing the open ends and terminal portions of the hollow fiber membranes in a first material held in the permeate pan or other header enclosure;
c) flowing a potting liquid into the permeate pan or other header enclosure over the first material, which potting liquid surrounds each hollow membrane and then solidifies becoming a solid mass which provides a fluid-tight seal to the outside of the hollow fiber membranes and which attaches and seals to the permeate pan or other header enclosure, the first material preventing the potting liquid or solid mass from closing said ends of the membranes; and
,d) removing the first material from said ends and terminal portions of the hollow fiber membranes and the permeate pan or other header enclosure.

26. A method of potting a plurality of hollow fiber membranes into a mass of solidified potting liquid comprising the steps of,
a) arraying a plurality of hollow fiber membranes in generally parallel relationship, each membrane having a terminal portion near a first open end of the membrane, the terminal portions of the membranes being generally adjacent each other; -
b) enclosing the first open ends and terminal portions of the hollow fiber membranes in a first material held in a container;
c) flowing a potting liquid in the container over the first material, which potting liquid surrounds each hollow membrane and then becomes a solid mass which provides a fluid-tight seal to the outside of the hollow fiber membranes, the first material preventing the potting liquid or solid mass from closing said ends of the membranes; and
,d) removing the first material from said ends and terminal portions of the hollow fiber membranes.
