Title:
SHORT FLOW CHANNEL MEMBRANE ELEMENT AND FILTER
Document Type and Number:
WIPO Patent Application WO/2023/246740
Kind Code:
A1
Abstract:
A short flow channel membrane element, comprising a membrane bag (1). The membrane bag (1) has a first long edge (101) and a second long edge (102) opposite to each other, and a first short edge (103) and a second short edge (104) opposite to each other. The membrane bag (1) is rolled along the extension direction of the first long edge (101) to form a membrane element. The membrane bag (1) is formed by folding a thin base membrane (100) along the first long edge (101). The thickness of the thin base membrane (100) is 0.005-0.08 mm, and the softness is 2.0-10g, such that the thin base membrane (100) can eliminate wrinkles formed at the first long edge (100) during membrane rolling. During filtering, water flow enters a raw water side, pure water formed by passing through the thin base membrane (100) flows out from the first long edge (101) side along a pure water flow channel (02), and the remaining concentrated water on the raw water side is discharged from the first short edge (103) and/or the second short edge (104) along an original water flow channel (01). The pure water side flow channel in the membrane element is shortened, such that the pure water production efficiency is improved, and the service life is long.
