Abstract
Relatively the specific high salinity ground water in Nineveh province were physically improved with freezing and melting treatment. Also, the algal treatment with Chara vulgaris as a biological treatment were applied, this algae have salt absorbance ability and precipitate it on the external algae surface . The results indicated that the complete freezing and slow melting gave low concentrations of the studied parameters, which depends on the melted water quantity after freezing, the impurity reduction efficiency %E of electrical conductivity, total alkalinity and total hardness with high values at the first treatment were (95 , 96 , 95%) respectively, the previous parameters were decreased to (73 , 74.7 and 77%) after the third treatment, also, the results were reported decreasing in case of partial freezing, so, the releasing percentage of electrical conductivity, total alkalinity, chlorides and sulfates to ( 56 - 55 - 42 and 85%) respectively. After six days of the biological treatment with Chara vulgaris algae indicates that the releasing percentage of total alkalinity and total hardness were decreased by ( 38.7 and 66%) respectively, finely it was found after 13 days of the treatment, the above parameters were raised to ( 55.1 and 92% ) respectively
