cze	Dealkoholizace modelových roztoků pomocí reverzní osmózy a diafiltrace	Byla ověřena možnost snížení obsahu etanolu v modelových roztocích pomocí reverzní osmózy pracující v režimu diafiltrace. Modelové roztoky obsahovaly kromě etanolu základní látky obsažené v pivu.Výsledky experimentů byly porovnány s matematickým modelem publikovaným v litaratuře.

eng	Dealcoholisation of standard solutions by reverse osmosis and diafiltration	One of the physical methods of beer dealcoholisation – reverse osmosis was chosen and studied. Four standard solutions were suggested for further research. These standard solutions contained basic substances of beer: water, ethanol and glucose. 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.	Dealcoholisation; Standard solutions; Membrane processes; Reverse osmosis; Beer
