Abstract

Procedimiento y sus correspondiente aparato para la reducción química del contenido de fosfatos del agua, por la añadidura, como mínimo, de un reactivo que forma una sal cristalina difícilmente soluble y produciendo el contacto del líquido con un material de inoculación promotor de la cristalización, caracterizado porque el contacto tiene lugar en un lecho de gránulos del material de inoculación que promueve la cristalización, en estado fluidificado y mantenido en fluidificación por la corriente de agua y porque la introducción del reactivo o reactivos se hace de manera que produzca una nucleación sustancialmente completa y heterogénea en el material de inoculación.
