This paper studied the effect of operating parameters on the efficiency of a small scale reverse osmosis with cellulose acetate (CA) membrane type has been studied. different samples were selected from several wells from different spots from Baghdad city. It was found that the highest system’s efficiency can be attained at 36 oC temperature, 250 pressure, pH=3 and 2000 ppm salinity. Also it has been found that the reflux ratio is proportional to the pressure and temperature of feed water, and this ratio is inversely proportional with the pH and salinity of feed water. Four samples with different salinity values were selected from wells in south of Iraq.

Keywords: Reverse osmosis, water desalination.
