“…18 Similarly, Larson observed that there was a difference in the reactions taking place in the anode and cathode of the Fe surface with and without a buffer. 19 Table 4 summarizes the anodic and cathodic reactions for Fe corrosion of Larson's study. The anodic reaction under the presence of buffer is the oxidation of a ferrous ion that yields a weak acid, H 2 CO 3 .…”

Laboratory-scale batch experiments (semicontinuously fed) were conducted using a two-level factorial experimental design to investigate principal factors and interactions affecting microbiologically influenced corrosion (MIC) of carbon (C) steel. Factors considered included the C source as chemical oxygen demand (COD), sulfate (SO 4 2-) concentration, calcium carbonate (CaCO 3 ) precipitation, and bacteria inoculation at 20°C. Yates' algorithm was applied to calculate main and interaction effects, and an empirical model indicating major trends was obtained. Experimental results showed CaCO 3 precipitation played a significant role in influencing the biocorrosion tendency of steel. In the supersaturated condition, SO 4 2concentration and bacterial inoculation had no appreciable effects on corrosion. In the undersaturated condition, the corrosion rate was affected significantly by SO 4 2concentration and bacterial inoculation. The effect of each factor on corrosion rate was explored.

“…Natural organic matter (NOM). Several studies (Lind Johansson, 1989;Sontheimer et al, 1981;Larson, 1966) found that NOM decreased the corrosion rate of both galvanized steel and cast iron. NOM was also found to encourage a more protective scale (Campbell & Turner, 1983) and alter the redox chemistry by reducing Fe +3 colloids to soluble fer-rous iron (Deng & Stumm, 1994).…”

This literature review summarizes the results of 100 years of corrosion studies, citing information from almost 300 peer‐reviewed articles to provide the water industry with an updated understanding of factors that influence the complex process of iron pipe corrosion. These factors include water quality and composition, disinfectant residuals, pipe age, scale formation, temperature, flow conditions, biological activity, and corrosion inhibitors. The authors review the reported role of these factors and highlight discrepancies in the literature. The article also discusses corrosion indexes that are intended to help control corrosion. In particular, it reiterates conclusions of prior studies regarding the Langelier index. Although this index continues to be widely used, it does not provide an effective means of controlling iron corrosion. Finally, a review of potential implications of existing and upcoming regulations, including the Lead and Copper Rule, the Disinfectants/Disinfection Byproducts Rule, and the Enhanced Surface Water Treatment Rule, for iron corrosion is also presented.

“…Organic matter: Large organic molecules can reduce iron corrosion rates by accumulating and coating the pipe network surfaces over time. The combination of organic and inorganic matter also assists in forming a stronger protective layer [ 29 ]. Yet, organic matter can alter the redox potential of the reaction system, thereby increasing the concentration of soluble ferrous iron in water.…”

The stability of drinking water distribution systems and the management of disinfection by-products are critical to ensuring public health safety. In this paper, the interrelationships between corrosion products in the network, microbes, and drinking water quality are elucidated. This review also discusses the mechanisms through which corrosive by-products from the piping network influence the decay of disinfectants and the formation of harmful disinfection by-products. Factors such as copper corrosion by-products, CuO, Cu2O, and Cu2+ play a significant role in accelerating disinfectant decay and catalyzing the production of by-products. Biofilms on pipe walls react with residual chlorine, leading to the formation of disinfection by-products (DBPs) that also amplify health risks. Finally, this paper finally highlights the potential of peroxymonosulfate (PMS), an industrial oxidant, as a disinfectant that can reduce DBP formation, while acknowledging the risks associated with its corrosive nature. Overall, the impact of the corrosive by-products of pipe scale and microbial communities on water quality in pipe networks is discussed, and recommendations for removing DBPs are presented.
