Concerning the blades corrosion in Mashhad power plant, it was known that the refined water was impure. One of the things that had to be checked out was the resin columns which were old and it was one of the reasons of water pollution. Sampling the anion and cat ion resins of these columns was done and at first bacterial test was done in Microbiology Lab and the result was positive. On the next step a sample of anion resin was SEM analyzed in Lab and cracks, slit and steel pollution were observed. According to the above mentioned pollution some biocides such as Formaldehyde and Peracetic Acid were suggested for eliminating bacterial pollution and using Sodium Dithionite or Chloridric Acid for elimination steel pollution as well. The results show that the use of these biocides can help considerably improve the process of refining water with resins.
