Resumo: Cross-flow microfiltration is an attractive alternative method for fluid clarification and sterilization in the brewing industries. The advantages are: elimination of filter aids, reduced beer losses and better product quality. The performance is still limited in flux terms due to membrane fouling. This work aimed to study the mechanism of fouling in beer microfiltration by means of calculating resistances. The experiments were conducted in batch with raw beer, in a cross flow ultrafiltration pilot unit. The membranes were tubular ceramics, with mean pore diameter of 0.2; 0.3; 0.4; 0.6 and 0.8 m and the pressures work were from 1.0 to 4.0 bar, at a temperature of 6±1ºC. From the model of resistances in series, the values obtained were of membrane intrinsic resistance, resistances due to polarization of concentration and colmatage.

O desempenho do processo é limitado pelo fouling causado na membrana. O objetivo deste trabalho foi realizar um estudo de fouling na microfiltração de cerveja por meio da avaliação das resistências. Os experimentos foram feitos em batelada com cerveja bruta, em uma unidade piloto de ultrafiltração tangencial. As membranas utilizadas foram do tipo tubulares cerâmicas, com tamanhos nominais de poros de 0,2; 0,3; 0,4; 0,6 e 0,8 m e as pressões de trabalho foram de 1,0 a 4,0 bar, na temperatura de 6±1ºC. Utilizando o modelo de resistências em série foram determinados os valores da resistência intrínseca da membrana, das resistências devidas à polarização de concentração e à colmatagem.Universidade Estadual De Maringá2008-02-12info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttp://www.periodicos.uem.br/ojs/index.php/ActaSciTechnol/article/view/69410.4025/actascitechnol.v29i2.694Acta Scientiarum.
