Background: Determination of water corrosion indexes is one of the affecting approaches on drinking water management. Corrosion can causes economical problems, reduce the useful life of water facilities, and health damages to consumers. The aim of this study was to survey of chemical quality and determination of the corrosion potential of the water distribution system in Bushehr city. Materials and Methods: In this cross sectional study, the sampling was carried out during one year from 7 stations. Values of Langelier, Ryznar, corrosivity and Puckorius indexes were calculated by using such parameters as pH, total dissolved solids, temperature, permanent and temporary hardness, and alkalinity. Results: The average values for pH, total dissolved solids, temperature, and alkalinity was obtained 7.5, 586.82 mg/L, 66.92 mg/L CaCO3. The corrosion indexes were calculated Langelier 0.28, Ryznar 7.24, corrosivity 12.02, and Puckorius 7.81. Conclusion: Bushehr city water is tends to be slightly scaling based on Ryznar index and corrosive based on other studied indexes. Overall, the water quality was tending to corrosive and, therefore, recommended to use corrosion resistance pipes in water transmission and network or lining the inner wall of pipes or correction the water quality. |
