It has been used along with other conventional techniques, achieving increases in chemical kinetics and a more efficient pollution removal. Conventional water treatments with surfactants are made by a biological action during the primary sedimentation. However, other possible treatments such as advanced oxidation processes have been explored. This article revises the most important investigations related to the subject and mentions some of the advantages photocatalysis has if compared to other systems.esFotocatálisisCorporación Universitaria LasallistaÁrea Metropolitana del Valle de AburráTratamiento de aguas residualesFotocatálisis heterogéneaAguas residualesAguas residuales industrialesArticle
