... Abstract Water chemistry is a factor in nearly all boiler tube failures. It contributes to the formation of scale, biofilms, and sludge, determines deposition rates, and drives the corrosion process. This chapter explains how water chemistry is managed in boilers and describes the effect...

... organisms can influence the occurrence or rate of corrosion, and the types of corrosion most often influenced by microbes. The chapter then discusses the formation of biofilms on the surface of metals. This is followed by a list of industries most often reported as being affected by microbiological...

The chapter, “ Microbiologically Influenced Corrosion ,” discusses the interactions of the biofilms that form on virtually all structural metals and alloys immersed in aqueous environments. These interactions can lead to many of the forms...

.... In all these environments, organisms in the water tend to attach to and grow on the surface of structural materials, resulting in the formation of a biological film, or biofilm. The film itself can range from a microbiological slime film on freshwater heat transfer surfaces ( Fig. 5 ) to a heavy...

..., although there are no specific studies on this. However, microorganisms adhere to this film and, as colonies of them grow, form a biofilm. This film consists of layers of microorganisms that can produce an exocellular polymeric matrix, which protects the colony from cleaning and disinfecting. Geometric...

The bacteria form a biofilm or slime with which they adhere to their host surface and create a microenvironment conducive to corrosion. Alternatively, the bacteria cause corrosion through direct chemical attack...

In addition, the metabolic process of the microorganism can produce a localized acid environment that changes the corrosion behavior...

The development of microbiological consortia allow anaerobes to flourish under biofilms that form in an aerated environment. These represent a differential aeration cell that acts just like a severe crevice. Also, the action...
