Industries in Indonesia significantly contribute to the economy by increasing foreign exchange earnings and creating job opportunities. However, industrial activities also negatively impact environment, particularly water pollution caused liquid waste containing oil emulsions. This research aims develop a membrane based on cigarette filters as an alternative cellulose acetate for separating emulsions water. Cigarette were processed into membranes with tannic acid (TA) ferric chloride (FeCl3) additives using vacuum-filtration coating technique. The resulting tested their characteristics performance, including morphological analysis, functional group hydrophilicity, uptake, porosity, pure flux, selectivity toward (artificial from CPO sodium dodecyl sulfate (SDS)) antifouling properties. results showed that exhibited more uniform pores, asymmetric structures, improved surface characteristics. addition of 2.4 mmol FeCl3 3.7 enhanced properties membranes, although it decreased flux. Membranes without (M1) (M2) compared separation efficiency, M2 lower flux (15.03 L/m2·h) than M1 (19.69 due reduced porosity. Although emulsion (97.80%) no significant improvement (97.79%), notably performance. demonstrated recovery ratio (FRR) 71.22%, higher M1’s FRR 46.01%, indicating effectiveness reducing fouling improving reusability. achieved high efficiency up 97%. These findings suggest base material adding can provide efficient environmentally friendly solution pollution.
