Microfiltration membrane and / or ultrafiltration, method of preparation of said membrane, and filtration method of a liquid through said membrane.

摘要

The invention relates to a membrane microfiltration and / or ultrafiltration comprising a polymer having POROS NOMINAL 0.01-10 (MU) M. MEMBRANE SPECIAL FEATURE IN ACCORDANCE WITH invention is that the membrane matrix ADDS AN ABSORBING ACTIVE POLIPIRROLIDON which is preferably Polyvinyl. USUALLY THE PRESENT Polyvinyl POLIPIRROLIDON in the membrane of 5-90% by weight or preferably in an amount of 3070% BY WEIGHT. Preferably, the membrane is hydrophilic and usually ASIMETRICA OR THIS constructed from different layers. THE NOMINAL SIZE pore membrane is 0.05-5 (MU) MY PREFERABLY 0.21.0 (MU) M while membrane is tubular, flat or capillary FORM. Furthermore, the invention concerns a method for the preparation of the membrane and a method of filtering of undissolved components in a liquid and / or simultaneous absorption of dissolved COMPONENTS IN LIQUID THROUGH MEMBRANE ACCORDING TO THE INVENTION . The method according to the invention is particularly suitable for separating components causing haze of a liquid, especially beer, THROUGH membrane according to the invention.
