- Application of double filtration with granular activated carbon for Atrazine reduction on water treatment processes Lina Fuentes López Claudia Amézquita Marroquín Patricia Torres Lozada Ingeniería Atrazine Adsorption drinking water granular activated carbon Atrazine is one of the most often used herbicides in the world. It reaches the surface water body by runoff, direct application or airborne dispersal. Conventional water treatment methods do not efficiently remove these types of pollutants, whereas granular activated carbon (GAC) adsorption is an adequate technique for the removal of organic compounds from water. In this work, the Atrazine reduction of water doped with two concentrations of Atrazine, was evaluated during the conventional treatment process (coagulation, flocculation, sedimentation and sand and anthracite filtration), followed by double filtration with two adsorbent granular media (vegetal and mineral GAC), which resulted in an efficient reduction of UV254 (86%) and Atrazine (99%). 2018 artículo científico 0012-7353 https://www.redalyc.org/articulo.oa?id=49657889024 https://www.redalyc.org/journal/496/49657889024/ https://www.redalyc.org/journal/496/49657889024/html/ https://www.redalyc.org/journal/496/49657889024/49657889024.epub https://www.redalyc.org/journal/496/49657889024/movil 10.15446/dyna.v85n205.68503 en http://www.redalyc.org/revista.oa?id=496 Dyna application/pdf Universidad Nacional de Colombia Dyna (Colombia) Num.205 Vol.85
