Abstract

The invention concerns the use of a microporous membrane constructed of polyether sulfon and a hydrophilization agent having a pore size which is within the range of between 0.1 and 1.2 microns for the filtration of beer. This membrane filter proves to be particularly suitable for the microbiological stabilization of the beer and for the separation of the turbid substances. The membrane makes it possible to remove the germs which are harmful to the beer and the harmful turbid substances and to simultaneously filter the beer with a high throughput and therefore economically and with low costs.
