Acetic cellulose membrane is made from acetic cellulose, formamide and acetone using variations of composition and condition. Flux and rejection value was influenced by the characteristic of the composition and thickness membrane, pressure and time of operation. The result showed that flux would decrease and the rejection would increase if the composition of the acetic cellulose too much, while the thickness didn’t influence rejection score, but decreased the flux. The optimum pressure of operation to obtain the hight flux and rejection on their process was 1,75 bar for membrane compotition 14,8% (w/w) of acetic cellulose and the thickness 0,083 mm for membrane with operation time 75 minute. The optimum result was flux permeate 432,92 L/m2 days and 93,09% rejection score.
