“…During chloramine disinfection periods in pipe A (A2), more crystalline goethite together with thick rounded crystals formed. For initial pipe B (B0), acicular goethite crystals predominated in the iron pipe surfaces, and its presence is indicative of more fragile corroding layers [10,17], while rounded formations were formed in a thick layer on pipes with disinfectant treatment (B1, B2).…”

“…The main mechanisms of corrosion inhibition take place on metal surfaces when the extracellular polymeric substances (EPS) of the biofilm impede the dissolution of Fe 2+ corrosion products [14]. Several researches reported the capacity of IRB/NRB to inhibit corrosion [10,15]. Therefore, microorganisms may play an important role in the occurrence and inhibition of red water.…”

“…Microbiologically influenced metal corrosion has been examined, including the impact of pure or mixed culture bacterial biofilms on the corrosion behavior of iron, copper, and their alloys [6][7][8]. The main types of bacteria associated with metals in terrestrial and aquatic habitats are sulfate-reducing bacteria (SRB), sulfur-oxidizing bacteria (SOB), iron-oxidizing/reducing bacteria (IOB/IRB), nitrate-reducing bacteria (NRB), and bacteria-secreting organic acids and slime [9,10]. Bio-corrosion is a result of interactions, which are often synergistic, between the metal surface, abiotic corrosion products, and bacteria and their metabolisms [6].…”

Red water has occasionally been observed in the water distribution system of Beijing following a change in the city's water source. Aged cast iron pipes from both affected and unaffected areas were used to establish experimental drinking water distribution systems under different disinfection conditions. The scale deposits formed under different conditions were characterized by X-ray diffraction and scanning electron microscopy, and the bacterial characteristics of the corrosion scales were determined using several molecular methods. The water quality changed less in pipe samples from the unaffected areas than pipes from the affected areas. The pipe samples from the unaffected area included predominantly α-FeOOH, Fe 3 O 4 , and γ-FeOOH, and 24.2% nitrate-reducing bacteria (NRB) were predominant with fewer ironoxidizing bacteria (IOB) being observed. The composition of corrosion products did not exhibit large variation over time although their crystallinity exhibited a slight decrease throughout the duration of the experiment. In contrast, in the pipe samples from the affected, α-FeOOH was the main compound with less γ-FeOOH and Fe 3 O 4 , and 3.3% IOB and 12% NRB with few IRB were observed. However, after transporting surface water containing disinfectants, the Fe 3 O 4 and dense corrosion layer formed, inhibiting the release of iron. Moreover, IRB and NRB became dominant. 22.6% and 34.3% NRB appeared in the pipes after chlorination and chloramination, respectively. The synergistic interaction of IRB and NRB with the corrosion layer played a large role in the release of iron from a cast iron pipe following changes in water quality.

Corrosion of carbon steel is investigated in the presence of Synechococcus sp. (S. sp., an aerogenic strain) with or without the coexistence of Pseudoalteromonas sp. (P. sp., an aerobic strain). Results of electrochemical and weight loss measurements suggest that the corrosion of carbon steel is continuous in S. sp. containing media while it is inhibited initially and accelerated finally in the coexistence of S. sp. and P. sp. This variation in corrosion rate is believed to be closely related to the difference in the growth and metabolism of two strains in different media. In media containing S. sp. alone, the slow reproduction of S. sp. leads to the relatively stable dissolved oxygen (DO) concentration and the continuous corrosion. In the case of S. sp. + P. sp., P. sp. consume DO and form protective biofilm at the initial stage, and then the death of P. sp. and the rapid reproduction of S. sp. cause the increase of DO concentration and the formation of porous corrosion products, leading to the change of corrosion rate.
