METHOD FOR PRODUCING SPIRAL WOUND TYPE MEMBRANE MODULE

摘要

PURPOSE: A method for producing a spiral wound type membrane module is provided to improve productivity and to efficiently supply purified water and sufficient flux since the water flow of the supplied original water is regular. CONSTITUTION: A channel frame on a filtered water side is made up, and then an assembly, a separation ion film + a channel material on the supplied water + a separation ion film, is prepared. Herein, a water collecting pipe is wound by rotating it slowly while the assembly is inserted between the channel material on the filtered water side. A supersonic melting method is used as a method to fix a reference channel on the filtered water side of the channel material frame on the filtered water side on a pipe.
