Title: (EN) METHOD FOR REMOVING BIOPOLYMER AGGREGATES AND VIRUSES FROM A FLUID
Abstract: front page image
(EN)

The present invention relates to a method for removing biopolymer aggregates and viruses from a fluid. In a first step, the biopolymer aggregates are selectively removed by filtration through a porous, polyamide-comprising shaped body having a native surface. In a second step, the biopolymer aggregate-free fluid is filtered through at least one suitable virus-retentive membrane.
