    摘要: 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.

    摘要: A method of reducing foaming of a liquid containing dissolved carbon dioxide during filtering. The carbonated liquid to be filtered is adjusted in pH to a value of 6.5 to 8.0 by the addition of an alkaline material which reacts with the dissolved carbon dioxide to remove the carbon dioxide from solution. The elimination of the dissolved carbon dioxide results in decreasing foaming during filtering and substantially increases the rate of filtration.

    摘要: An arrangement for protecting the filtering fibers inside a wine-treating vat to protect it against premature soiling, said arrangement comprising a preliminary filter constituted by a small mass of filtering fibers filling a short tubular upright rising above the conventional opening in the upper cover of the vat which is assumed to be completely filled with filtering fibers. The small prefiltering mass of fibers carried for instance by a basket removably fitted inside the upright can be readily replaced. This ensures a much longer life for the actual large filtering mass of fibers inside the vat. An annular wall may surround the tubular upright and rise above the latter so that the wine poured into the annular gap between the upright and the wall may flow thence over the edge of the upright into the latter and into the vat.
