Abstract

UN FILTRO PARA POLIMEROS QUE FLUYEN DISPONE DE UN ELEMENTO FILTRANTE (30) QUE SE DESPLAZA PROGRESIVAMENTE EN CONTRACORRIENTE DESDE UNA POSICION QUE COMUNICA LAS ZONAS SUPERIOR E INFERIOR (34, 43) HASTA LA POSICION DE DESCARGA POSTERIOR. EN ESTA ULTIMA POSICION, SE FUERZA EL PASO DEL POLIMERO FILTRADO A TRAVES DE UN SEGMENTO DEL ELEMENTO, EN DIRECCION CONTRARIA AL AVANCE DE LA CORRIENTE. EL AVANCE DEL FILTRO SE REALIZA POR ETAPAS QUE SE ALTERNAN CON LA ACTIVACION DE LA BOMBA (90) PARA CREAR UNA PRESION DE RETRODESCARGA. LAS ETAPAS SE ESTABLECEN DE TAL FORMA QUE CADA PORCION DEL FILTRO PERMANEZCA EN LA POSICION DE DESCARGA POSTERIOR AL MENOS DURANTE DOS ETAPAS CONSECUTIVAS.
