The study of corrosion and scaling in drinking water distribution system in the Malekshahi city of Ilam Provinc, spring 93

One of the major problems of water utilization scaling and corrosion, which is a physical and chemical reaction between a metal and its environment is done and leads to material changes its properties. In this study corrosion and scaling index gained for malekshahi city's drinking water supply.
The desired parameters in accordance with the standard method of water and wastewater tests were tested and corrosion index Langelier, Rayznr, corrosion and Puckorius were calculated using equations and diagrams.
The results indicate that in accordance with the indices of corrosion Langelier index (-o.4), Rayznr (7.59), corrosion (11.59) and Puckorius (6.44), in terms of drinking water, city malekshahi the corrosive medium.
Evaluation of corrosion indices showed that drinking water is corrosive malekshahi city. And to compare parameters of water quality in the city malekshahi indicates that the concentration measured parameters except alkalinity is all in the standards of Iran and EPA.
