| titleOfInvention | Spiral reverse osmosis membrane element, method of manufacturing the same, and its use method |
| abstract | A spiral reverse osmosis membrane element that improves impregnation property of a sealing resin at edges of a membrane leaf and can effectively prevent micro-leaks, by using, for example, a porous support having a structure capable of sufficiently impregnating therein a sealing resin, a method for manufacturing the same, and a use method of the same are disclosed. The spiral reverse osmosis membrane element comprises a cylindrically wound body comprising a perforated core tube and, spirally wound therearound, a separation membrane, a feed-side passage material and a permeation-side passage material in a laminated state, and a sealing portion for preventing a feed-side liquid and a permeation-side liquid from being mixed together, wherein the separation membrane facing through the permeation-side passage material has a structure that a porous support and a skin layer are successively laminated on a non-woven fabric layer, and the sealing portion sealed with a sealing resin is provided at the edges of the separation membrane, wherein the separation membrane is impregnated with the sealing resin at least up to the vicinity of the skin layer through the porous support. |
