The Study of Groundwater Treatment by Household Reverse Osmosis System

Water desalination systems, especially household reverse osmosis, have become widely used in Iraqi homes due to lack of water that conforms to the global standards of drinking water in recent times. The ability of RO system to treat groundwater has been tested within a period of time. Water samples have been analyzed before and after entering the system for physical, chemical and biological parameters. The results showed that the RO system was efficient in removal different types of contaminants, and the removal efficiency was as follows Electrical Conductivity (EC) (92.9 %), Turbidity (78.5 %), Total Hardness (T. H) (96.8 %), Calcium (Ca) (97.1 %), Magnesium (Mg) (96.4 %), Sulfate (So4) (92.2 %), Nitrate (No3) (92 %), Sodium (Na) (91.6 %), Potassium (K) (84.9 %), Chloride (Cl), Bicarbonate (Hco3) (87.7 %), Cadmium (Cd) (100 %), Iron (Fe) (80 %), Lead (Pb) (100 %). The biological results showed that the ability of RO system to decrease the numbers of different types of bacteria. From these results, the Ro system was efficient in treating groundwater.
