Corrosive Behavior and Physic-Chemical Characterization of Filtration Tanks
Abstract
Most drinkable water supplied to the public in Mexico City comes from deep
wells which extract water from the subsoil. Before being distributed, it is
treated in steel filtration tanks. This water must be subject to evaluation
through physic-chemical and bacteriological analyses in order to determine its
quality. However, doubts always remain over the influence of the components
of this water on the corrosive behavior of the filtration tanks. In light of this,
this article studies the physic-chemical characterization values of water and
presents the results. This has also enabled the analysis of the corrosion speed
of filtration tanks components, boilers and water-cooled systems, where incrustations
in pipes, obstructions and loss of heat transfer efficiency occur,
rendering drinkable water bad tasting and, after some time, causing pitting
corrosion although this type of corrosion only causes serious problems in the
long term.
