Abstract

LA SUSPENSION SE INTRODUCE DE MODO REGULAR Y EN CIRCULACION CONTINUA EN UNA INSTALACION DE MICROFILTRACION QUE DISPONGA, COMO MINIMO, DE UNA MEMBRANA SEMIPERMEABLE A TRAVES DE LA CUAL SALGA EL LIQUIDO PERMEADO. EL PROCEDIMIENTO SE CARACTERIZA PORQUE LA CANTIDAD DE PERMEADO QUE VA SALIENDO SE SUSTITUYE PAULATINAMENTE POR UN LIQUIDO DE LAVADO DIFERENTE AL PRIMERO, DE MODO QUE LA CANTIDAD TOTAAL DE LIQUIDO DE LAVADO QUE SE ADICIONA REPRESENTE DE 1 A 12 VECES EL VOLUMEN TOTAL DE LA SUSPENSION DE PARTIDA. A CONTINUACION SE SEPARAN EL LIQUIDO Y LA SUSPENSION MEDIANTE INSTALACIONES CONVENCIONALES DE FILTRACION O DE SECADO. EL PROCEDIMIENTO RESULTA PARTICULARMENTE ADECUADO PARA EL TRATAMIENTO DE SUSPENSIONES FINAS DE PIGMENTOS, TALES COMO LAS QUE SE PRODUCEN DURANTE LA SINTESIS DE ESTOS.
