分離膜エレメントおよびその使用方法、ならびに水処理装置
Document Type and Number:
Japanese Patent JP6973650
Kind Code:
B2
Abstract:
Provided is a spiral-type separation membrane element with a lengthened supply-side flow path, wherein: to prevent deformation of a wound body and damage to a membrane surface and to enable operation with stable permeability and separation performance even when a pressure loss of a supply fluid is large, the spiral separation membrane element comprises a perforated center pipe, a plurality of separation membranes each having a supply-side surface and a permeation-side surface, a supply-side flow path material, and a permeation-side flow path material; the plurality of separation membranes are arranged overlapping such that the supply-side surfaces face each other and the permeation-side surfaces face each other; the supply-side flow path material is disposed between pairs of the supply-side surfaces of the separation membranes; the permeation-side flow path material is disposed between pairs of the permeation-side surfaces of the separation membranes; and the lengths of openings in supply-side end faces of the separation membranes and the widths of sealing members on the supply side and the permeation side of the separation membranes satisfy a prescribed relationship.
