Desalination of groundwater for several districts in Baghdad-Iraq using reverse osmosis membrane.

This paper has been achieved to desalinate the brackish groundwater for several districts located in Baghdad the capital of Iraq which are Amiriya, Shurta 5 ,and New Baghdad by using reverse osmosis (RO) Unit. ULP 1812-50 RO type has been used for desalination in this paper. The system has accomplished the percentage of water recovery that ranged between (18.18 - 33.33)% and the percentage of salt rejection that ranged between (97.07 - 99.29)%. As well as the high efficiencies of removal for the physio-chemical parameters of the raw groundwater which are Electrical conductivity, EC (95-99)%, Turbidity(100)%, Total Hardness (100)%, Ca (95-100)%, Mg (84-93)%, Cl (70-96)%, SO₄ (85-100)% and NO₃ (73-93)%. These results have showed us that the RO technique is suitable to produce freshwater from brackish water. [ABSTRACT FROM AUTHOR]
