Abstract

Procedimiento para la purificación de las aguas de lavado o residuales, resultantes en el tratamiento de papel viejo, respecto de sustancias ajenas, especialmente respecto de sustancias que se comportan de forma hidrófoba, que se caracteriza porque el agua que ha de ser purificada es mezclada con jabones de calcio y el jabón de calcio que actúa como colector para las sustancias que reaccionan de forma hidrófoba es separado por medio de sedimentación, flotación, centrifugación o tamizado juntamente con las sustancias que reaccionan de forma hidrófoba y el agua purificada es devuelta de nuevo al proceso de tratamiento.
