摘要：The high content of chloride salts, and other dissolved salts such as; SO4 2- , Na + , and the presence of coliform criteria lead to non-compliance of brackish water as clean water. Decreasing of the content of water’s parameters in brackish water can be done by treatment of Coagulant Aid and Ion Exchanger that followed serially by membrane technology reverse osmosis (RO). The flowing process of treatment in this study are : coagulant aid, filtration using sediment polipropylena (SPP), and absorption using manganese greensand, then continued by Ion Exchanger using synthetic resin anion and cation resin. As a finishing treatment is filtration micro using membrane of Reverse Osmosis (RO). The combination of coagulant aid, ion exchangers and reverse osmosis (RO) water treatment brackish obtained on removal parameters: Chloride of 2028 ppm, Turbidity 2.74 NTU scale, color 45 units PtCo, Iron 0.22 ppm, Total Disolved Solid (TDS) 3366 ppm, Total Hardness 621.43 mg/L, CaCO3, Organic Substances 19.84 mg/L KMnO4, Fluoride 0.62 ppm, Nitrate 0.06 ppm, Nitrite 0.64, Zinc 0.08 ppm, Sulfate 40.46 ppm, and Detergent at 0.12 mg/L LAS. Processing brackish water based on RO membrane techno combined with coagulant aid and ion exchanger are able to fulfill all of clean water requirements parameters
