ORTEGA RAMIREZ, Angie Tatiana  y  SANCHEZ RODRIGUEZ, Natalia. Advanced Treatments for Wastewater Purification. Cienc. Ing. Neogranad. [online]. 2021, vol.31, n.2, pp.121-134.  Epub 31-Dic-2021. ISSN 0124-8170.  https://doi.org/10.18359/rcin.5343.

This article seeks to identify the most crucial breakthroughs in wastewater purification. For this, a detailed explanation is given about the importance of water and its current state, considering harmful pollutants for the aquatic ecosystem. The study takes scientific articles, journals, dissertations, and textbooks published between 1936 and 2019 in different databases such as Google Scholar, Virtual Pro, Ambientalex.info, and Science Direct. Accordingly, it describes the advantages and disadvantages provided by each of the existing water treatments, specifically advanced treatments, determining innovative techniques, benefits, applications, and operations on an industrial scale. The results suggest that implementing advanced wastewater treatments gives rise to technological development focusing on water management, reaching a higher level of water pollutant removal. Besides, the exchange techniques and membrane technologies are functional to carry out effective and efficient removal processes. Even though the advanced oxidation method degrades pollutants, it is not functional due to its high operating cost.

Palabras clave : Wastewater; emerging pollutants; ion exchange; membranes; advanced oxidation; advanced treatments.
