Abstract

A submerged-type hollow fiber membrane module and a method for manufacturing the same is disclosed, which is capable of realizing a great sealing strength between a module case and a bundle of hollowfiber membranes without an additional centrifugal molding apparatus, the method comprising forming a bundle of hollow fiber membranes held together and fixed by a first potting material, wherein one end of each of the hollow fiber membranes is open; putting the bundle of hollow fiber membranes in a module case and fixing the bundle of hollow fiber membranes in the module case by forming a second potting material on the first potting material.

Description

technical field [0001] The present invention relates to a hollow fiber membrane module for water treatment, in particular to a submerged hollow fiber membrane module and its potting process. Background technique [0002] Water treatment that cleans a liquid by removing pollutants therefrom may use a heating method, a phase change method, or the use of a separation membrane. [0003] The separation membrane usage method can achieve high reliability because it is suitable for stably supplying desired water quality according to the size of pores formed in the separation membrane. In addition, the method of using a separation membrane does not require a heating process. In this regard, the method of using a separation membrane is advantageous in that it can be widely applied to various separation processes using microorganisms, which may be affected by heating processes. [0004] The separation membrane may include a flat type membrane having a flat cross section and a hollow ...
