The basic parameters for mass transfer of alcohol and extract have been determined. The beer flow rate influences both efficiency and selectivity of the alcohol separation. The results suggest that, in order to achieve a satisfactory selectivity in the alcohol free- and low-alcohol beer production, using dialysers with hollow fibre Cuprophan membranes, the beer flow rate should not be less than 500 ml min-1 m-2. © 1993 Chapman & Hall, London.
