Efisiensi dan Efektivitas Pencucian Kimia pada Membran Ultrafiltrasi Sistem Aliran Dead End Proses Pengolahan Limbah Emulsi Minyak

Abstract

The application of dissociation of oil-water emulsion by using membrane hadshown the happening of fouling phenomenon. This phenomenon caused by foulingmaterial tend to have the character of irreversible and reversibel. This foulant canbe conducted with chemical cleaning. Target of this research is to study efficiencyand efectivness at chemical cleaning with cleaning chemical agent (NaOH, HCland HNO3) for reduction foulant of oil-water emulsion. The operation has beendone by forward and dead-end stream system of Membrane UF acetate cellulose.Flushing to be conducted for 30 minute with pressure 0,5 bar, so also with chemicalcleaning (NaOH, HCl, and HNO3). Variation concentration of chemical agentcleaning are 0,1, 05, and 1 N. Comparison oil-water emulsion is 5% : 95% whichtreatment for a long of 60 minute with operating pressure variation of 0,5; 1 and 1,5bar. The result of this research obtained, that NaOH 1 N more efficient eliminatefoulant compared to HCl and HNO3. Mean cleaning effectiveness is equal 29,82 %after cleaned with tired NaOH but downhill effectiveness till 16,40 % if using HCland 8,80 % while be used HNO3.
