Corrosion and scaling potentials of rural water distribution network in different climate zones of Kermanshah province, Iran

Corrosion control is an important parameter to supply safe drinking water considered by the World Health Organization. This study is intended to determine the scaling and corrosion potentials of drinking water in rural distribution networks during 2009-2017 in different climate zones of Kermanshah province, Iran. The most commonly used corrosion indices, Langelier saturation index (LSI), Ryznar stability index (RSI), Puckorius scaling index (PSI), aggressive index (AI), and Larson–Skold index (L-SI), were calculated. Statistical analysis was executed to examine the significant differences in water corrosion and scaling indices between different climate zones. Statistical analysis showed significant differences in water chemical characteristics related to corrosion and scaling potentials between different climate zones (except temperature). Statistical analysis also indicated significant differences in water corrosion and scaling indices (P
