Abstract

Un proceso para preparar un agente de floculación que comprende: a) mezclar un conjunto de reactivos que comprenden un aldehido alifático y una sal que contiene un radical de amoníaco asociado, en un medio acuoso; b) hacer reaccionar mediante calentamiento la mezcla obtenida en (a) hasta que se obtiene un líquido substancialmente incoloro; c) añadir opcionalmente un ácido mineral fuerte para llegar a un pH final de entre 1 y 3, y d) hacer reaccionar el líquido obtenido en (b) o (c) con una solución de tanino acuosa, bajo agitación.
