    摘要： The invention relates to a process for the removal of components causing turbidity, from a fluid, by means of microfiltration, whereby the fluid is beer, wine, fruit juice, bacterial suspension, blood, milk, enzyme suspension, etc. According to the invention, the fluid to be treated is fed across an asymmetric membrane having a pore structure such that the pores on the feed side of the membrane are larger than the nominal pore size and the pores of nominal pore size occur in the cross section toward the permeate side, the filtered off components are back-flushed from the membrane and are subsequently carried away with the fluid. The nominal pore size is usually 0.1-5.0 .mu.m and preferably 0.2-1.0 .mu.m. The membrane may be tubular, flat or capillary. Back-flushing takes place intermittently with a frequency of 1 second to 10 minutes for 0.1-1 second at a counter pressure of 0.5-5 bar. The feed velocity is preferably below 2 m/s and the pressure difference over the membrane is less than 0.5 bar.

    摘要： The invention relates to a microfiltration and/or ultrafiltration membrane consisting of a polymer having nominal pores of 0.001-10 .mu.m. The special feature of the membranes according to the invention is that the matrix of the membrane incorporates an active adsorbent which is preferably polyvinyl pyrrolidone. Usually the polyvinyl polypyrrolidon is present in the membrane in an amount of 5-90% by weight and preferably in an amount of 30-70% by weight. Preferably the membrane is hydrophilic and is usually asymmetric or is constructed of different layers. The nominal pore size of the membrane is 0N05--5 .mu.m and preferably 0.2-1.0 .mu.m, while the membrane is tubular, flat or capillary. Furthermore, the invention relates to a method of preparation of the membrane and to a method of filtration of undissolved components from a liquid and/or the simultaneous adsorption of dissolved components from the liquid by means of the membrane, the method according to the invention is especially suitable for the removal of components causing turbidity from a liquid, especially beer.
