Title:
SEPARATION MEMBRANE ELEMENT
Document Type and Number:
WIPO Patent Application WO/2024/095643
Kind Code:
A1
Abstract:
This separation membrane element has a thread diameter of a supply side flow channel material other than intersections of a net shape, the thread diameter being smaller than a thread diameter of the intersections, has θ×(1-Lp/Lq)2>15, wherein, in a plane parallel to the flow direction of supply water and vertical to the planar direction of the supply side flow channel material, P is a point on the outer circumference of a cutting plane other than the intersections where the distance between the cutting plane and a separation membrane is minimum, Q is a point on the outer circumference of the cutting plane where the distance on the same side as the separation membrane on the downstream side of supply water from P is maximum, Lp is the distance between P and the separation membrane, Lq is the distance between Q and the separation membrane and θ is an elevation angle from P to Q, and has the proportion of the area of the cutting plane relative to the area of a diagram formed with a line forming a convex hull enclosing, among the outer circumference connecting P with Q on the cutting plane, the outer circumference closer to the separation membrane surface and the outer circumference further from the separation membrane surface of 70% or more and Lp of 15% or less of the thickness of the supply side flow channel.
