  4. Abstract:
  5. Increasing demand of fresh water, and limitation water resources, with respect to world economic growth brings up the importance of utilization of saline water. At the current research the sensitivity analysis of ROSA was conducted. For this analysis, a single stage reverse osmosis is designed for well water specifi cation in southern Tehran under following condition: Feed fl ow: 40 m3/h and membrane Element: BW30–400 FR. The sensitivity analyses for all chemical element of base water were performed. As a result of sensitivity analysis shortest sensitivity gap, belongs to boron, and longest sensitivity gap, belongs to calcium. Which refl ects, under the same conditions, the least element to be eliminated ion is boron and the most eliminated ion is calcium, in fact the order of omitting is from lowest to the highest interval in following order “Boron, Ammonia, Nitrate, Potassium, Sodium, Bicarbonate, Fluoride, Chloride, Silica, Strontium, Barium, Sulfate, Magnesium, Calcium.” The optimum element which could result proper membrane selection achieved. © 2009, Taylor & Francis Group, LLC
