Abstract

Procedimiento para la descontaminación de aguas de proceso alfa y beta activas, especialmente de la producción de combustibles nucleares, caracterizado porque el agua de los procesos se ajusta a un pH de nos 5,8, a continuación, y bajo continua agitación, se mezcla con CaO o Ca(OH)2 hasta alcanzar un valor pH previamente dado y después de cómo mínimo 5 minutos la suspensión se descompone mediante una centrífuga en sus componentes líquidos y sólidos, conteniendo estos últimos las sustancias contaminantes.
