Abstract
Método de espesar lodo, caracterizado porque comprende las etapas de introducir en el lodo un polielectrolito catiónico, de dar tiempo para que se desarrolle una estructurade flóculos, de disponer el lodo sobre una superfice a través de la cual puede escurrirse libremente líquido, de tal manera que se mantenga la estructura de flóculos, y de sacar el lodo espesado de dicha superficie
