| titleOfInvention | Spiral reverse osmosis membrane elements, methods for their preparation and methods of use thereof |
| abstract | Provided is a spiral reverse osmosis membrane element, a method for producing the same, and a method for using the porous support having a structure capable of sufficiently impregnating the sealing resin, thereby improving the impregnation of the sealing resin at the membrane leaf end to effectively prevent micro leakage. do. A spiral reverse osmosis membrane element comprising a separator, a cylindrical winding body spirally wound around a perforated center tube in a laminated state, and a seal for preventing mixing of the supply side fluid and the permeate side fluid. The separator facing through the permeate side channel member has a structure having a skin layer on the porous support, and a sealing part sealed by a sealing resin is provided at an edge of the separator, and the separator is at least skinned through the porous support. It is impregnated with the said sealing resin to the vicinity of a layer, It is characterized by the above-mentioned. |
