| Abstract | ||
| The aim of this research is to study the potential of scale formation and corrosivity of the water using in Al-Najebia power station cooling system in Basrah province, south Iraq. water indices such as langelier saturation index, Ryznar stability index, Pukuriuos scaling index and Larson ratio have been used for predicting the corrosive, scale forming . The study is based on the obtained corrosion and scale data for the period from Jan.2012 to Dec. 2012 , samples were collected from Al-Najebia Power Station cooling system water , the analytical results were used to calculate the indices, because of seasonal flucations in water characteristics, sampling was performed twice monthly. The quantitative analytical methods were employed. All indices were calculated the mean values of langelier saturation index (-0.3317), Ryznar stability index mean value was (7.7833), Puckurius scaling index mean value was (6.216) while the mean value of Larson Ratio was (29.59) and preliminary results confirmed that the studied water has a tendency to corrosion and scale formation, also the results revealed that the indices were correlated with measured metal ions. | ||
