Polymeric porous hollow fiber membrane
PURPOSE: To provide a polymeric porous hollow fiber membrane which exhibits excellent fractionation performance and excellent permeability in treatment of a variety of aqueous fluids and also shows sufficient strength when incorporated into a module or used to treat a fluid, and which is excellent in aging stability in these performances and characteristics and is also excellent in membrane performance recoverability by washing, and which is especially suitable for treatment of a polyphenol-containing beverage and is expected to effectively harmonize the flavor of such a beverage.SOLUTION: A polymeric porous hollow fiber membrane of the present invention is characterized in that    This polymeric porous hollow fiber membrane is also characterized in that the adsorption of polyphenol per a surface area of 1 m2 defined by the inner and outer surfaces of the membrane is from 50 to 500 mg.
