Abstract : This paper presents the study of the effect of variation of different operating conditions on the performance of RO unit. This was achieved theoretically by brackish water RO (Reverse Osmosis) desalination model using ROSA software. Then an experimental test rig was constructed to perform experiments to simulate environmental conditions and operational parameters for RO units. Results of theoretical modeling at constant feed water parameters showed that: Feed water pressure increases the permeate flow rate and the recovery ratio increase while brine rejected, permeate TDS and specific energy consumption decrease. Feed water TDS increases the permeate flow rate and the recovery ratio decrease while brine rejected, permeate TDS and specific energy consumption increase. Feed water temperature increases the permeate flow rate, permeate TDS and the recovery ratio increase while brine rejected and specific energy consumption decrease. Feed water flow rate increases the permeate flow rate, specific energy consumption and the recovery ratio increase while the brine rejected and permeate TDS decrease. Samples of experimental output parameters were used as ROSA input parameters to check the accuracy of experimental results. However, there were deviations between the experimental results and ROSA results that did not exceed 10 %.
