Durability considerations for mitigating corrosion caused by biogenic sulfuric acid in sewerage systems

Abstract

Abstract In sewerage systems, the corrosion process caused by microorganisms, has been studied. This affects the structural integrity of the concrete drainage pipes and the sewage treatment plants, This article is a review of research which focuses on the study of how to reduce the production of hydrogen sulfide, how to improve the resistance of concrete through the use of additives and the implementation of antimicrobial techniques to reduce bacterial growth, This review allowed us to find a way to improve the physical simulation of exposure to the corrosive medium through chemical tests, as well as the optimization and choice of the type of zeolite that would be incorporated into the mixture with which concrete pipes are normally manufactured. for sewers in Colombia improving their durability conditions.
