Evaluation of scaling and corrosion potential of lake katwe brine.

Abstract

In this study, corrosiveness and scaling potential of Lake Katwe brine in Kasese district are evaluated based on the chemical analyses of 11 samples of brine from different locations and the physicochemical parameters experimentally to determine their concentrations. (Kassedde et al 2012). Piper plot shows that majority of the samples are mixed Na-Cl and Na-HCO3. (Kassedde et al 2012). The results of the physicochemical parameters were used to calculate the most popular corrosion and scaling indices such as Langelier index (LI), aggressive index (AI), Ryznar index (RI), Puckorius index (PI) and Larson–Skold index (LS). Results of LI show that 100% samples have corroding tendency. AI has the same result as 100% of the water has scaling tendency. RI suggests that 100% of the samples have rigorous corrosive tendency. Values of the PI suggest that all the samples were corrosive. Finally, the LS values show that 9.1% of the samples have scaling tendency and the remaining have corrosion tendency. In general, the lake katwe brine in Kasese district shows both corrosive and scaling tendencies, which can cause severe damage to the machineries in the industries.
