Abstract

THE EFFECT OF PRESSURE ON REVERSE OSMOSIS MEMBRANE TO PROCESSING BRACKISH WATER INTO FRESH WATER THROUGH WATER TREATMENT PROCESS Gita Putri Kusumawardani, 2016, 73 Pages, 14 Tables, 38 Pictures, 4 Enclousers Brackish water is water that occurs because of the intrusion of the sea water (brine) to freshwater. To change the brackish water into fresh water, it is developing a treatment technology with a semipermeable membrane that can only be penetrated by water molecules. This brackish water treatment technology known as reverse osmosis systems. The main objective of this study was to obtain potable fresh water from the brackish water which has a salinity level 0.5 - 17 ppt with Reverse Osmosis Membrane Filtration, by varying the pressure (1,2,3,4, and 5 bars). Type of membrane used is a Thin Film Composite with a pore size of 0.0001 μm. Before being passed to the membrane, given some of the raw water pretreatment such as coagulation, sedimentation, filtration and manganese zeolite filtration with a cartridge filter. The parameters observed in this study namely pH, salinity, TDS, turbidity, levels of iron (Fe) and manganese content (Mn). Results from the study showed that the best optimum pressure at 5 bar with the resulting in value of TDS reached 227 mg/l , 0.29 NTU turbidity , salinity of 0,001 ppm, iron levels reached 0,044 ppm, manganese contents amounted to 0.0113 ppm, NaCl rejection amounted to 61.54 % and the increase in the permeate flux of up to 74.20 % . From these results it can be stated that fresh water is produced in accordance with quality standards based PERMENKES RI No. 416/MENKES/1999.
