Abstract

Reverse Osmosis is an excellent process applied in the works of water desalination usually for the production of water relatively free of salts for industrial purposes especially in establishments causing thermal pollution, as in Al-Dora refinery.
The aim of this research is to analyze the water parameters, including (Total Dissolved Solids (TDS), pH-value, Turbidity, residual chlorine, Total Hardness and Alkalinity) which affect the efficiency of the (RO) unit in AL-dora refinery water treatment plant, and comparing concentrations of these parameters with the allowable standards. The weekly mean of daily readings have been taken for the period from 2008-2011, where the removal efficiency(RE%) of the unit was good and within the standard specifications , the relation between RE% for TDS and the other variables are strong during the period (The correlation coefficient magnitude is 0.865). ,except the year 2010,which is not within the standard specifications because of :Tigris river level descent, badness of pretreatment system lead to increase the salts and damaged membranes for desalination.
Key Words: Reverse Osmosis, TDS, Removal Efficiency.
