Sensitivity of Corrosion and Scale Potentials: A Case Study of Qareh Sou River, Northern Iran

An important parameter in assessment of quality is its chemical properties. Corrosion and scale are the most important topics in quality of chemical water, since they have important roles in drinking water distribution network and economic aspects. This study investigated chemistry quality, corrosion and scaling potentials in Qareh sou basin for industrial utilization and drinking water purification. In this study six hydrometric station data and 0 samples were used during 20 0-20. To measure corrosion the indices of Langlier, Rysnar, Puckorius, and Larson and Aggressive corrosion were used. According to LI, RI and PI Qareh sou basin is corrosive. AI indicated that this river`s water is scaling, but Larson index showed more sensitivity than other indicators. Sensitivity of the indices represents allowable parameter to prevent corrosion and scaling. With more precise control of these parameters can be prevented from causing economic losses.
