Microbiologically induced corrosion of concrete in sewer structures: A review of the mechanisms and phenomena

Corrosion and sulfur-related bacteria

“…With respect to the bacteria, Desulfotomaculum and Desulfovibrio are the two mostly reported SRB genera concerning MIC (Hao et al, 1996;Satoh et al, 2009). Other microbial species that can cause MIC include, for example, proteobacteria, firmicutes and nitrospira (Wu et al, 2020). In addition, certain archaea exhibit a sulfate reducing metabolism and may contribute to the MIC as well (Santo Domingo et al, 2011).…”

“…Other factors that can affect the formation of H 2 S (aq) include, biochemical oxygen demand, sulfate concentration and temperature of the wastewater, turbulence and hydraulic retention time (House & Weiss, 2014;US EPA, 1974;Wu et al, 2020).…”

“…concrete structures and have attracted huge attention (Grengg et al, 2018;Wu et al, 2020), partly due to the significance to society and the large-scale builds nowadays. The emphasis of the current chapter is on sewer structures when discussing MIC of concrete.…”

“…For MIC of concrete that occurs especially in sewers, sulfur-related bacteria, e.g. sulfate-reducing bacteria (SRB) and sulfur-oxidizing bacteria (SOB), are among the most relevant (Sun, 2015;US EPA, 1974;Wu et al, 2020). For MIC of carbon steel, SRB are the most well-known and studied bacteria; while several other types, e.g.…”

“…Sulfur-related bacteria can be involved in a number of processes, generating sulfur and sulfur compounds (Islander et al, 1991;Little & Lee, 2007). The consequences include material corrosion and different types of cracking (Enning & Garrelfs, 2014;Jia et al, 2019;Little & Lee, 2007;US EPA, 1974;Wu et al, 2020). This chapter will focus on discussing several aspects of corrosion of concrete in sewer structures and carbon steel caused by sulfur-related bacteria.…”
