| Abstract: | Summary Irradiated styrene-grafted cellulose acetate membrane was used for the separation of ethanol by reverse osmosis. Ethanol separation from molasses based fermentation broth resulted in separation efficiency of 90% at an operating pressure of 1400 psig. Lower permeate flux was observed with fermented broth compared to aqueous ethanol. |
