Abstract

There is a growing interest in the development of highly efficient and sustainable treatments for the removal of pollutants that are difficult to remove by traditional methods. In this sense, the objective was to explore and critically analyze emerging technologies in industrial wastewater treatment, seeking to provide a comprehensive overview of the most recent advances in this field, assessing their efficiency, sustainability, and feasibility of various innovative methodologies, as well as to identify the strengths and limitations of each technology. To this end, a systematic literature review was carried out using the PICOC method and a screening of scientific articles by means of PRISMA, obtaining a sample of 95 publications. The results showed that the efficiency of the emerging technologies is above 90% for most organic, inorganic, and microbiological pollutants, with the adsorption method standing out. Despite the advantages offered by these technologies, there are still challenges, such as high costs and validation at industrial scale. It is concluded that the current industrial wastewater treatment landscape is characterized by a wide range of emerging technologies that seek to address the specific challenges associated with the diversity of pollutants; these innovations focus on advanced adsorption methods, photocatalysis, advanced oxidation, bioremediation, nanofiltration, among others, each under unique approaches, to achieve more effective and sustainable industrial wastewater management.
