Abstract
The application discloses a filtering device for virus removal filtration of a protein-containing feed liquid and a method for virus removal filtration of a protein-containing feed liquid, and relates to the technical field of biological filtration. The filtering device comprises a filtering unit, a packaging layer, a liquid inlet channel, a filtrate channel and a filtering layer, wherein the filtering layer comprises a virus removal membrane, the LRV of the virus removal membrane for virus impurities is not less than 4, and the protein yield is not less than 98%, the virus removal membrane comprises a pre-filtering layer and a separation layer for intercepting viruses and having a pore size smaller than that of the pre-filtering layer, and at least one pre-filtering layer is arranged on the surface of the side of the virus removal membrane away from the filtrate guide screen. The filtering device has the advantages of simple structure, convenient operation, good virus removal effect of the virus removal membrane on the protein-containing feed liquid, and the like.
