Abstract

The aims of this study were determine the optimum velocity of centrifuge. This study started from synthesis of silica shells, sample purification, and preparation of membranes. Membrane quality tested using dead-end reactor. Technique of membrane process used phase inversion technique with various centrifuge velocities 500, 600, and 700 rpm. Analyzed parameters were the concentration of chloride and Total Dissolved Solid (TDS). Tests of membrane structure and morphology used spectrofotometry Fourier Transform Infra Red (FTIR) and Scanning Electron Microscopy (SEM). This study came up to the conclusion that centrifuge velocity 600 rpm resulted in highest chloride rejection. The highest chloride rejection was 53,87 and the highest TDS removal was 80,02.
