Abstract
In the current the sugar cane process, the liquid sugar cane is purified by physical and chemical processes that need much energy and produce waste. Membrane process separation is alternative way for purifying it. In this research, membrane was prepared from cellulose acetate by phase inversion method with acetone as a solvent and formamide as additive. The experiment was conducted by varying cellulose acetate concentration and evaporation period. Cellulose aseatat, acetone and formamide with a particular composition is stirred for 3-4 hours until homogeneous. Mixture is then filled into the bottle and closed tightly and left for 1 day. Furthermore, the mold is poured on flat glass and evaporated during the allotted time. Matter and its lining membrane is inserted in a tub filled with water at a temperature 2 o C for 5 minutes, the membrane was then dried.. Performance of membrane produced was tested determination by liquid sugar cane. The result of the experiment showed that the best weight ratio of cellulose acetate:acetone:formamide was and evaporation period were 12.5:5.2:3.5 and 45 second respectively; the membrane produced have volumetric flux, rejection of TSS and permeation of sucrose were 6.1698 l/m 2 .hour, 91.12% and 89% respectively.
