Biocorrosion of mild steel in drinking water conditions and disinfection

Abstract

[Excerpt] Introduction: Corrosion in drinking water distribution system is a costly phenomenon, mainly due to the replacement of altered pipes. Bio..corrosion is also a problem in term of public health because of the suspected protection brought by the corroded surface to potentially harmful microorganisms, especially bacteria. The protection effect of corrosion is particularly relevant in the presence of disinfectant. In drinking water are present the conditions leading to microbialy induced corrosion: bacteria and metal-containing substrata joined closely together as biofilm attached to distribution system pipe walls.
