Title (DE) VERFAHREN ZUR ABTRENNUNG VON BIOPOLYMER-AGGREGATEN UND VIREN AUS EINEM FLUID
(EN) METHOD FOR SEPARATING BIOPOLYMER UNITS AND VIRUSES FROM A FLUID
(FR) PROCÉDÉ POUR LA SÉPARATION D'AGRÉGATS DE BIOPOLYMÈRE ET DE VIRUS D'UN FLUIDE
Abstract:
(DE) Die vorliegende Erfindung betrifft ein Verfahren zur Abtrennung von Biopolymer-Aggregaten und Viren aus einem Fluid. In einem ersten Schritt erfolgt die selektive Entfernung der Biopolymer-Aggregate durch Filtration durch einen porösen, Polyamid umfassenden Formkörper mit einer nativen Oberfläche. In einem zweiten Schritt wird das von Biopolymer-Aggregaten befreite Fluid durch mindestens eine geeignete virusretentive Membran filtriert.
(EN) The invention relates to a method for separating biopolymer units and viruses from a fluid. In a first step, biopolymer units are selectively removed by filtration through a porous mold comprising polyamide and having a native surface. In a second step, the fluid freed of biopolymer units is filtered through at least one suitable virus-retentive membrane.
(FR) L'invention concerne un procédé pour la séparation d'agrégats de biopolymère et de virus d'un fluide. L'élimination sélective des agrégats de biopolymère par filtration à travers un corps moulé poreux comprenant un polyamide, possédant une surface naturelle est effectuée lors d'une première étape. Lors d'une deuxième étape, le fluide débarrassé des agrégats de biopolymère est filtré à travers au moins une membrane appropriée retenant les virus.
