SPIRAL MEMBRANE MODULE

摘要

Provided is a spiral membrane module for which the connection method and configuration are not complicated and which has a connecting structure wherein membrane elements can be connected to each other securely using a central tube. The spiral membrane module accommodates a plurality of spiral membrane elements (E) connected in series inside a pressure container and is characterized in that the membrane elements (E) are provided with a central tube (3) that extends from anti-telescoping parts (4) and has engaging parts (3a) on the outer circumference, and in the provision of a connecting part (10), which straddles the engaging parts (3a) of adjacent membrane elements (E) and engages with both engaging parts (3a).
