Treatment system and treatment method employing spiral wound type membrane module |
摘要 |
In a treatment system, a spiral wound type membrane module is provided on a preceding stage of a reverse osmosis membrane separation device for performing pretreatment with the spiral wound type membrane module. The spiral wound type membrane module is formed by charging a pressure vessel with a spiral wound type membrane element. The spiral wound type membrane element is formed by covering a spiral membrane component, prepared by winding a plurality of independent or continuous envelope-like membranes on the outer peripheral surface of a water collection pipe, with a separation membrane and further covering the same with an outer peripheral passage forming member.
