Membrane ultrafiltration is one alternative technology to produce a high quality cane sugar with reasonable cost, because its ability to produce a brighter color and lower impurities as well as sulphur free of product. This technology can reduce process steps, chemical and energy demand, so that the production cost is potentially reduced significantly. This research work was aimed to study the performance of various membrane filtrations in the application for clarifying sugar cane juice, covering the achievable flux, membrane rejection againstimpurities, and quality of the filtered juice. The experiments were conducted according to the principle of cross flow using three different transmembrane pressures of 0.7, 1.4, and 2.1 bar and cross flow rate of 0.42 m/s. Various membranes were studied in this experiments both commercial ultrafiltration membrane and ultrafiltration membrane prepared in our laboratory. Sugar cane juice before and after clarification were characterized by measuring the parameters of brix, sucrose concentration, solution color, clarity, and pH. Thepolisulfone membrane, which was prepared in our laboratory, produced fluxes in the range of 25-30 L/m2.h at the transmembrane pressures of 0.7-2.1 bar. The membranes increased clarity of the juice from app. 10 to 60% of transmition and reduced color up to 80-90%, comparable with the results of the commercial ultrafiltration membrane
