Spiral Membrane Element |
| abstract |
A spiral type membrane element capable of increasing an effective membrane area and also reducing operating energy in a membrane element having a limited outer diameter is provided. A plurality of membrane leaves L with a permeate-side channel member 3 interposed between the opposing separation membranes 1, a supply-side channel member 2 interposed between the membrane leaves L, a membrane leaf L, and A spiral membrane element comprising a perforated center tube (5) on which a supply-side flow passage material (2) is wound, and a sealing portion for preventing mixing of the supply-side flow passage and the permeate-side flow passage, wherein the sealing portion includes the membrane The leaf L includes both end sealing portions 11 in which two side ends on both sides in the axial direction A1 are sealed with an adhesive, and the thickness T1 of the both ends sealing portion 11 is 390 µm to It is characterized in that it is 540 μm. |
