Corrosion Induced by Acidithiobacillus Thiooxidans in Concrete Systems in Sewage Treatment Plants
Abstract
The present work aims to discuss the corrosion induced by microorganisms (MIC) in reinforced concrete by the bacteria Acidithiobacillus thiooxidans, in sewage treatment station. The physical characteristics and chemical reactions responsible for the decrease in pH values on the surface of reinforced concrete parts will be presented. The steps in the process of consolidating the pathology of civil works depend on the establishment of the biofilm coating, allowing the production of acids that will reduce the pH values and the project's useful life.
