RIOS, John Fredy; CALDERON, Jorge Andrés; ECHEVERRIA, Félix  e  PENUELA, Gustavo. Design of a model system for the study of corrosion of pipe material and its contribution in deterioration of drinking water quality. Rev.fac.ing.univ. Antioquia [online]. 2008, n.43, pp. 102-113. ISSN 0120-6230.

Distribution systems can affect drinking water quality because pipe conditions and system operation. Some parameters like residual chlorine, pH, color and turbidity can be modified during the distribution, because pipe material can show deterioration in these systems by the water corrosivity. Several studies about this topic had used both real system and laboratory equipment for performing of tests. The most used apparatus nowadays is the model distribution system; it has several advantages like flexibility and easiness for design. A revision in journals is used for defining the design characteristics of model distribution system. It will be used for studying the interaction between the water and the pipe wall. Metallic materials used in secondary distribution system will be used in this study with the purpose of determining the attack to the inner surface of pipes and the causes of deposits formed on them; such as identifying the effects of this interaction in water quality.
