The objective of this study was to investigate the removal efficiency of Reverse Osmosis (RO) . RO is also capable of very high rejection of microorganisms and synthetic organic .The main objective of pilot-scale testing was to evaluate TDS removal using actual continuous-flow source wastewater and commercial-size membrane elements. Three Ro pilot systems was operated during the study to treat waste water . Pilot-scale tests were performed on a commercial model LFC3 (9500gpd(. RO was terminated at a water recovery of approximately 87.2%. The clean water flux (CWF) was measured before and after the run The salinity (conductivity), NH4, NO3 and Na concentration levels are too high for discharge into the water environment. The chloride concentration level is too high for discharge into the sewer system.
