Abstract
(EN)
The object of the present invention is to provide a method for the stable production of a composite semipermeable membrane with which there are few skin layer defects and the filter rate is high. The present invention is characterized in that a method for producing a composite semipermeable membrane wherein a skin layer is formed on the surface of a porous substrate comprises a step for impurity removal with which, before the skin layer is formed on the surface of the porous substrate, the impurities that adhere to the surface of the porous substrate are removed.

La présente invention concerne un procédé de production stable d'une membrane semi-perméable composite présentant peu défauts de la couche de peau et un débit de filtre élevé. La présente invention est caractérisée en ce qu'un procédé de production d'une membrane semi-perméable composite selon lequel une couche de peau est formée à la surface d'un substrat poreux comprend une étape d'élimination des impuretés, grâce à laquelle, avant la formation de la couche de peau à la surface du substrat poreux, les impuretés qui collent à la surface du substrat poreux sont éliminées.
