Performance of Cellulose Acetate Membrane for Water Treatment in Riau Coastal Region

membrane technology is growing rapidly today, including in the field of water treatment coastal. The objective of this research is to preparred cellulose acetate membrane for coastal region in Riau, Sumatra, Indonesia. The perfomance cellulose acetate membrane to investigated perfomance cellulose acetate membrane for coastal region water treatment. The main objective of this study was make of cellulose acetate membranes for water treatment process to drinking water, determine the effect of operation pressure of the cellulose acetate membrane flux and determine the effect of rejection cellulose acetate membrane for color, hardness, turbidity and chloride parameters. Membranes prepared by phase inversion method with variation of cellulose acetate composition and operation pressure of 2-8 bars. Membrane characterization consists of calculation of membrane flux and rejection with coastal water as a feed. The research concluded that cellulose acetate membrane can be made by phase inversion method. Based on the research results cellulose acetate membranes can treat water at the coast of Riau, Sumatra, Indonesia. The influence of the operating pressure of the flux is higher the pressure, the higher flux generated. Cellulose acetate membranes are capable of removing components on coastal water such as turbidity, color, hardness and chlorides
