Assessment of scaling and corrosion potential of drinking water resources of Iranshahr

Abstract

The aim of this study was to evaluate corrosion and scaling potential of drinking water resources Iranshahr in order to considering necessary solutions to solve possible problems including internal corrosion of pipes, deterioration of water quality and reduce of water transfer capacity of distribution network system. The data showed that Langelier index ranged between −1.53 to −0.96, Ryznar index between 9.63–10.54, Aggressive index between 12.04 and 12.91, and Puckorius index between 9.05–10.68 for drinking water resources Iranshahr. Studied indices indicated that the drinking water in Iranshahr can be considered as corrosive.
