Liquid-filtration membrane and module, and method for making

A method for making a membrane module for use in liquid filtration, the method comprising:

• providing a quantity of an adhesive in a storage vessel;
• immersing first ends of a plurality of liquid-filtration membranes into the adhesive up to a first length along the first ends;
• applying a quantity of a driver liquid above the quantity of the adhesive in the storage vessel, wherein the driver liquid is less dense than the adhesive, such that a weight of the driver liquid applies a force on the adhesive so as to drive some of the adhesive into an interior of each of the plurality of liquid-filtration membranes up to a second length along the first ends, wherein the second length is greater than the first length;
• removing at least some of the driver liquid from the storage vessel;
• solidifying the adhesive;
• cutting the plurality of liquid-filtration membranes at a point that is between the first length and the second length such that the first ends of the plurality of liquid-filtration membranes are disconnected from one another and are sealed so as to prevent liquid flow therethrough;
• providing a support structure including a header;
• and
• mounting a second end of each of the plurality of liquid-filtration membranes into the header so as to permit fluid communication between a permeate chamber defined at least in part by the header and the interiors of the plurality of liquid-filtration membranes.
