Abstract

La invención se refiere a una composición y un proceso para purificación de agua contaminada, especialmente para la remoción de contaminantes dañinos como arsénico, además de la remoción de otros contaminantes microbianos dañinos e impurezas particuladas suspendidas, para hacer adecuada el agua para consumo humano. Se ha encontrado que una composición de floculación/desinfección, la cual comprende ciertos hidróxidos de doble capa, los cuales contienen al menos un catión divalente seleccionado y al menos un catión trivalente seleccionado, proporciona remoción de arsénico intensificada.
