Abstract

Procedimiento de clarificación de líquidos y suspensiones en particular de las aguas residuales urbanas o industriales, potables, de procedimientos o residuales, que utilizan la técnica de floculación lastrada con una etapa de inyección en el líquido a clarificar, pretratado o no con una masa de contacto o lastre, constituida por un material granular, tal como particularmente arena, y un polímero, seguida de una etapa de floculación que lleva la formación de un copo lastrado y una etapa de decantación acelerada, recirculándose el indicado lastre en la etapa de floculación, bien sea tal cual, o después de la limpieza, según un primer régimen de recirculación que asegura la extracción del lastre contenido en el copo lastrado y por consiguiente, particularmente la separación de la arena con los lodos, la eliminación del copo en forma de lodos y el reciclado del lastre limpio hacia la floculación, caracterizado porque comprende un segundo régimen de recirculación de energía más débil que el primer régimen asegurando la extracción del lastre contenido en el copo lastrado, asegurando este segundo régimen la transferencia del copo lastrado a la etapa de floculación mientras que el porcentaje de lastre en el floculador es superior a un nivel predeterminado, permaneciendo este segundo régimen en servicio durante la puesta en acción del primer régimen, pero deteniéndose seguidamente el funcionamiento de dicho primer régimen, siendo los dos sistemas utilizados de forma alterna con el fin de mantener el porcentaje de lastre a un nivel predeterminado.
