Polysulfone membrane and composite membrane |
| abstract |
【Task】 An object of the present invention is to provide a composite reverse osmosis membrane having both high water permeability and high solute removability without using a modification treatment step after film formation. [Solution] The layer (A layer) having a depth of 1 μm from the surface has an average pore diameter of 200 nm or less, an average porosity of 40 to 75%, and a metaphenylenediamine diffusion amount of 1 × 10 −3 mol / m 2 or more. A polysulfone membrane, which is 2 × 10 −3 mol / m 2 or less. [Selection figure] None |
