eng	Dealcoholization of Model Solutions by Reverse Osmosis and Diafiltration	The present paper focuses on dealcoholisation of a beer by reverse osmosis. Four of these model solutions contained basic substances of the beer: water, ethanol and glucose. Substances, which are responsible for a good aromatic profile of the beer (n-propanol, isobutanol, isoamylalcohol), were also included in the fifth model solution. The effect of the substances added to the solution, and influence of retentate flow on the permeate flux were studied. The results of initial experiments were taken as the basis for further diafiltration process, where significant reduction of the ethanol concentration in the retentate was expected. Experimental results were compared with values calculated from mathematical model found in the cited literature. The diafiltration process studied is suitable for the dealcoholisation of investigated mixtures.	Dealcoholization;model solutions;membrane processes;reverse osmosis;beer
