Abstract
ESTA INVENCION SE REFIERE A UN PROCESO Y APARATO DE FUNCIONAMIENTO CONTINUO PARA REEMPLAZAR EL LIQUIDO EN UNA SUSPENSION LIQUIDA DE UN MATERIAL FIBROSO CON OTRO LIQUIDO POR FORMACION DE UN LECHO (32) DE ESTE MATERIAL EN UNA SUPERFICIE DE FILTRO MOVIBLE Y POR DESPLAZAMIENTO DEL LIQUIDO PRESENTE EN ESTE LECHO CON EL OTRO LIQUIDO. EL LECHO (32) DE MATERIAL ESTA FORMADO EN UNA SUPERFICIE DE FILTRO CILINDRICA (7) INSTALADA VERTICALMENTE POR DEBAJO DE LA SUPERFICIE DE LIQUIDO EN UN RECIPIENTE (14) Y LO CONDUCE CONTINUAMENTE HACIA DELANTE PARA FILTRACION Y SE LLEVAN A CABO VARIOS DESPLAZAMIENTOS SUCESIVOS DE LIQUIDO PARA MANTENER UNA DIFERENCIA DE PRESION HIDROSTATICA A LO LARGO DEL LECHO FORMADO (32), EL CUAL ES CONDUCIDO CONTINUAMENTE HORIZONTALMENTE HACIA DELANTE, Y A SU TRAVES FLUYEN LIQUIDOS HORIZONTALMENTE DURANTE LA FILTRACION Y DESPLAZAMIENTO DEL LIQUIDO.
