- Abstract
This study evaluates the scaling and corrosion potential of drinking water in the distribution network of Kermanshah city during 2018, based on water corrosion and scaling indexes. One hundred and twenty samples were collected from 24 stations throughout the drinking water distribution network in the winter and the summer seasons. Some parameters including temperature, total dissolved solids (TDS), pH, alkalinity and calcium hardness were determined using standard methods. The mean values of pH, TDS, total alkalinity, calcium hardness and temperature were 7.7, 299.08 mg/L, 194.33 mg/L as CaCO3, 156.95 mg/L as CaCO3, and 23.43°C in the summer and 7.5, 320.03 mg/L, 188.31 mg/L as CaCO3, 165.24 mg/L as CaCO3, and 11.76°C in the winter, respectively. The scaling and corrosion potential were evaluated based on average values of Ryznar stability index (RSI), Langelier saturation index (LSI), Aggressive index (AI) and Puckorius scaling index (PSI) that were 7.26, 7.31, 0.21, 0.09 in the summer and 12.19, 11.98, 10.12 and 9.52 in the winter, respectively. According to the results of this study, the drinking water distribution network of Kermanshah tend to be corrosive.
