DEPURACIÓN DE TRATAMIENTO DE AFLUENTE CON ALTO CONTENIDO DE METALES PESADOS QUE AFECTE A LAS ESTRUCTURAS METÁLICAS.

The present investigation carries out a Systematic Review of the scientific Literature to analyze the purification methods of treatment of affluent with a high content of heavy metals that affects metallic structures, reported in the scientific literature. A total of 805 studies obtained from the Scopus, IEEE, Web of Science, Scielo, Elsevier, Springer databases were initially retrieved; with the Google Scholar, Semantic Scholar and IEEE Xplore search engines; Finally, 16 were included in this investigation. As a fundamental result, 12 methods of purification of affluent contaminated with heavy metals were identified. For the present investigation, the conventional treatment methods for developing countries were especially significant. The results obtained in several investigations indicate that metallic structures are affected when they are in contact with tributaries with a high content of heavy metals, mainly when the tributary is related to industrial waters.
