MULTILAYER SEPARATION MEMBRANE |
| 摘要 |
An object of the present invention is to provide a multilayer separation membrane having excellent performance on both removal of suspended solids in water and adsorptive removal of metal ions in water. A multilayer separation membrane of the present invention includes: a porous adsorption layer including substantially a polymer having chelating functional groups; and a porous clarification layer and the porous clarification layer is disposed neater to a raw water-side than the porous adsorption layer. |
