| Sumario: | This work compares the permeated flow and the quality of the obtained product in the process of beer clarification by crossflow microfiltration. The membrane used in the present study was a tubular ceramic membrane with a 0.2 µm nominal pore diameter, at 6 µ 1µC and 1, 2, 3 and 4 bar of pressure. Samples of the feed and permeate were analyzed. Additionally, the fouling mechanism was studied: complete, partial, internal blockade of pores and cake filtration. The results show a 28.75% reduction in color and 95.65% in turbidity at 4 bar. The study of fouling showed that the mechanism used for the pressures of 1 and 3 bar was the complete blockade of pores, whereas for the pressures of 2 and 4 bar, the cake formation was the mechanism used. |
