Abstract

Brine water- which derived from seawater reverse osmosis reject water(SWRO), has an high amount of dissolved solids (TDS). Brine wateralso contains NaCl concentrates, that in huge quantities has certain economic values, as a raw material in chlor-alkali industry, the regeneration of resin-ion exchange and any other substantial benefits. The early stage of NaCl recovery process from reject water starts with separation phase of NaCl from various mineral impurities exist mostly in Calsium and Magnesium. The main purpose of this research was to discover optimum condition of natural flocculant Moringa oleifera (MO) on decreasing impurities mineral brine water from SWRO reject water, so that it could produce NaCl solution high concentrate. In this study, response surface methodology (RSM) approach was used to optimize concentration of NaOH as precipitant, flocculant dosage and flocculation velocity gradient (G), and the results will be measured as maximum decreasing of TDS impurities.The final result of this research shows TDS impurities is succeeded to be decreased by the Moringa oleifera’s extract in the amount of 84-90%.
