Abstract
Método de tratamiento de agua para reducir el contenido de sílice disuelta de la misma, que comprende al menos una etapa de adsorber la sílice disuelta, en donde se hace pasar el agua a través de un reactor que alberga un material granular adsorbente que consiste en granos de hidróxido de hierro (III) y/u oxihidróxido de hierro (III) y una etapa de regenerar la potencia adsorbente del material granular, consistiendo en poner el material granular en contacto con una base y al menos un cloruro.
