Membrane module

摘要

A membrane module and method of making are provided. Exemplarily, the membrane module is adapted for use with an electrochemical apparatus. The membrane comprises a fabric made from a synthetic fiber such as nylon, where the nylon is woven into ripstop nylon fabric. The membrane module includes the membrane around which is formed a frame, comprising exemplarily, high-density polyethylene (HDPE) or polypropylene, which frame provides support to the membrane as well as support and structure to internal electrodes.
