Abstract

Introduction: Scaling and corrosion is one the most important indices in water quality
evaluation. Occurrence of scaling or corrosion may create disorder in economy of water
and wastewater industry. In addition, corrosion produces by - products in water leading to
health problem and reduction of water pipe life-time. In this study, the condition of scaling
and corrosion in Bandar Abbas water network was evaluated.
Methods: In this cross- sectional study, pipe water network of Bandar Abbas was
divided into 15 sections and, randomly 3 samples were taken from each section.
Langleier and Rysnar indices and Marble test were used for water quality analysis.
Results: Based on Rysnar index, in 20% of samples, water was neutral and in 33% as
slightly corrosive. Based on Langleier index in 6.6% of samples, water was neutral and in
93.4% were slightly corrosive. Marbel test showed that all of the tested samples were
corrosive.
Conclusion: We showed that, there is corrosion potential in Bandar Abbas water network
so as proper interference is required. Evaluation of indices shows that, there is significant
difference among indices findings; therefore it seems that mono-index evaluation is likely
unable to determine the corrosion status or scaling condition. To evaluate water stability or
corrosiveness condition, simultaneous indices are recommended.
