MEMBRANE MODULE AND MEMBRANE CASSETTE

摘要

A membrane element is provided between a pair of water collecting cases. Water collecting spaces in which permeate having penetrated through the membrane element is collected are formed in the water collecting cases. The water collecting case of one membrane module and the water collecting case of the other membrane module are coupled via coupling portions. The coupling portions have flow holes. The water collecting space of the water collecting case of the one membrane module and the water collecting space of the water collecting case of the other membrane module communicate with each other via the flow holes of the coupling portions.
