Reasons for Corrosion in Waste Water Treatment Works
Municipal sanitation systems were developed for the efficient evacuation and treatment of effluent and waste water. Sewerage system designs have evolved a great deal, but microbial induced corrosion of the structures remains a growing problem for the responsible authorities and their engineers throughout the world.
Microbial induced corrosion happens when sulphates in biological waste are converted into sulphides through a biological process under the anaerobic conditions below the waste-water line in the sewers. Above the waste-water line, the hydrogen sulphide gas that is released in this process forms aggressive and corrosive condensates with water such as sulphurous and then sulphuric acid.
