Spiralförmig gewickeltes Membranelement |
摘要 |
A spiral wound type separation membrane element includes a spiral wound type membrane component formed by superposing separation membranes of membrane materials supported on nonwoven fabric members on both surfaces of a permeated liquid passage forming member and bonding three sides with an adhesive thereby defining an envelope-like membrane, mounting an opening of the envelope-like membrane on a water collection pipe and bonding the same with an adhesive and spirally winding the envelope-like membrane around the outer peripheral surface of the water collection pipe along with a raw liquid passage forming member. The outer peripheral surface of the envelope-like membrane forming the spiral wound type membrane component is covered with a sheath member, and anti-telescopic members are mounted on both end surfaces of the envelope-like membrane respectively. Each of the aforementioned components forming the spiral wound type separation membrane element is made of heat-resistant alkali-resistant plastic. |
