DE SOUSA, Cristina; CORREIA, Angelina  y  COLMENARES, María Cristina. Corrosion and incrustations in the drinking water distribution systems: Review of control strategies. Bol Mal Salud Amb [online]. 2010, vol.50, n.2, pp.187-196. ISSN 1690-4648.

The aim of this review was to analyze control strategies of contamination caused by the formation of corrosion and incrustations based on factors affecting deterioration of distribution systems of potable water as well as its influence on the quality of water supplied to the consumer. Distribution systems can affect the quality of drinking water due to the conditions of the pipes and the system’s operation. Corrosion, incrustations, and deposits in the distribution network major problems in the drinking water industry. These may affect health, public acceptance of the water supply and the cost of supplying reliable water. We conclude and recommend that, in order to control corrosion and the formation of incrustations, one must select appropriate materials and a sound system design, apply proper chemical treatment (adjusting pH, alkalinity, oxygen, the use of corrosion inhibitors) and use coatings and paints resistant to corrosion in order to protect the walls of the pipes.
