“…Metal corrosion has been examined in distribution systems, including both electrochemical corrosion and microbiologically influenced corrosion (Lin et al, 2001;Starosvetsky et al, 2001). Because very little energy can be generated during the oxidation of ferrous to ferric iron, a large quantity of iron needs to be oxidized to support the growth of iron oxidizing bacteria.…”

a b s t r a c tTo understand the impacts of different plumbing materials on long-term biofilm formation in water supply system, we analyzed microbial community compositions in the bulk water and biofilms on faucets with two different materials-polyvinyl chloride (PVC) and cast iron, which have been frequently used for more than10 years. Pyrosequencing was employed to describe both bacterial and eukaryotic microbial compositions. Bacterial communities in the bulk water and biofilm samples were significantly different from each other. Specific bacterial populations colonized on the surface of different materials. Hyphomicrobia and corrosion associated bacteria, such as Acidithiobacillus spp., Aquabacterium spp., Limnobacter thiooxidans, and Thiocapsa spp., were the most dominant bacteria identified in the PVC and cast iron biofilms, respectively, suggesting that bacterial colonization on the material surfaces was selective. Mycobacteria and Legionella spp. were common potential pathogenic bacteria occurred in the biofilm samples, but their abundance was different in the two biofilm bacterial communities. In contrast, the biofilm samples showed more similar eukaryotic communities than the bulk water. Notably, potential pathogenic fungi, i.e., Aspergillus spp. and Candida parapsilosis, occurred in similar abundance in both biofilms. These results indicated that microbial community, especially bacterial composition was remarkably affected by the different pipe materials (PVC and cast iron).

“…In addition, biofilm was reported to contribute to the formation of corrosion cells on metal surfaces due to the growth of microorganisms; i.e., biofilm comprises several bacterial genera that can accelerate metal corrosion (Lin et al, 2001;Starosvetsky et al, 2001). The majority of MIC investigations have addressed the impact of pure or mixed culture bacterial biofilm on corrosion behavior (Beech and Gaylarde, 1999).…”

Chlorine CorrosionReclaimed water distribution system a b s t r a c tThe effects of disinfection and biofilm on the corrosion of cast iron pipe in a model reclaimed water distribution system were studied using annular reactors (ARs). The corrosion scales formed under different conditions were characterized by X-ray diffraction (XRD), energy dispersive spectroscopy (EDS), and scanning electron microscopy (SEM), while the bacterial characteristics of biofilm on the surface were determined using several molecular methods. The corrosion scales from the ARs with chlorine included predominantly a-FeOOH and Fe 2 O 3 , while CaPO 3 (OH)$2H 2 O and a-FeOOH were the predominant phases after chloramines replaced chlorine. Studies of the consumption of chlorine and iron release indicated that the formation of dense oxide layers and biofilm inhibited iron corrosion, causing stable lower chlorine decay. It was verified that iron-oxidizing bacteria (IOB) such as Sediminibacterium sp., and iron-reducing bacteria (IRB) such as Shewanella sp., synergistically interacted with the corrosion product to prevent further corrosion. For the ARs without disinfection, a-FeOOH was the predominant phase at the primary stage, while CaCO 3 and a-FeOOH were predominant with increasing time. The mixed corrosioninducing bacteria, including the IRB Shewanella sp., the IOB Sediminibacterium sp., and the sulfur-oxidizing bacteria (SOB) Limnobacter thioxidans strain, promoted iron corrosion by synergistic interactions in the primary period, while anaerobic IRB became the predominant corrosion bacteria, preventing further corrosion via the formation of protective layers. ª

“…Morphology and composition of corrosion scales and deposits occurring in DWDSs have been studied so far by many research groups [4][5][6][7][8][9][10]. Corrosion scales usually include inorganic iron-based compounds such as iron(III) oxide-hydroxides (goethite (α-FeOOH), akaganeite (β-FeOOH), lepidocrocite (γ-FeOOH)), iron oxides (hematite α , and y 2 to 4), iron(II) hydroxide (Fe(OH) 2 q, and iron sulfides (e.g.…”

“…Chemical and phase composition of corrosion scales and deposits has been determined using different methods such as elemental analysis [4,15], X-ray diffraction (XRD) [6,9,10], scanning electron microscopy (SEM) [8,9,10,15], and vibrational spectroscopy [15]. The occurrence of water sediments is the main reason of water meters failure in DWDSs.…”

Preliminary studies on the sediments collected from water meters of Krakow water supply system were performed in the cooperation with the Municipal Water Supply and Sewage. Creation and deposition of sediments on the measuring devices installed in the water supply system is a serious technological and economical problem for water companies, defectively operating for this reason water meters must be replaced. It is evident that knowledge of the chemical and phase composition of sediments is an important step towards resolving the problem of impurities in water supply systems. Four different samples of sediments, coming from water meters, were investigated using the proton-induced X-ray emission, the X-ray diffraction, the Fourier transform infrared and Raman spectroscopy. The X-ray methods revealed presence of amorphous and fine-crystalline phases as well as high content of iron-based compounds. As a crystalline phase, the most frequently appeared: goethite, lepidocrocite, iron oxides (hematite, maghemite, magnetite), calcium carbonate, and quartz. In one of the samples, the nanocrystalline phase was found and identified as hydrous iron oxyhydroxide ferrihydrite. Vibrational spectroscopy methods confirmed the composition of crystalline phases as well as enabled to estimate the abundance of amorphous phase in samples.
