Abstract

SE PRESENTA UN CONJUNTO DE FILTRO MICROPOROSO, QUE EN ALGUNOS MODOS, TIENE PRESION DE ALIMENTACION ALIMENTADA A LAS PAREDES EXTERNAS DE LAS FIBRAS MICROPOROSAS (13) QUE COMPRENDEN EL FILTRO. EN OTRAS FORMAS SE LE HACE CRUZAR LAS PAREDES DE LAS FIBRAS (13) POR LA APLICACION DE UNA PRESION REDUCIDA A LOS LUMENES DE LAS FIBRAS (13). SE PRESENTAN VARIAS FORMAS DE REMOLINO DE LAS FIBRAS, NO REQUIRIENDO NINGUNO DE DICHOS MODOS UNA ETAPA DE PRESURIZACION DEL MEDIO DENTRO Y ALREDEDOR DE LAS FIBRAS (13) ANTES DEL EMPIECE DEL REMOLIDO. EN PARTICULAR FORMAS DE REMOLINO, LOS PASOS INICIALES DEL REMOLINO COMPRENDEN CONCLUIR EL SUMINISTRO DE ALIMENTACION A LA SUPERFICIE EXTERIOR DE LAS FIBRAS (13) Y ELIMINAR SUSTANCIALMENTE EL FILTRADO RESTANTE DE LOS LUMENES DE LAS FIBRAS (13) EN ALGUNAS REALIZACIONES. EL FILTRO COMPRENDE UN CARTUCHO DE FILTRO (10) QUE INCLUYE UN MANOJO DE FIBRAS (13) ALOJADO DENTRO DE UN CUERPO CERRADO PRESURIZABLE (12). EN OTRAS REALIZACIONES EL FILTRO COMPRENDE UNO O DOS MANOJOS DE FIBRAS (1029 SUSPENSOS DENTRO DE UN RECIPIENTE ABIERTO (101). LA INVENCION REDUCE EL NUMERO DE CICLOS DE PRESURIZACION REQUERIDOS DEL MEDIO DENTRO Y ALREDEDOR DE LAS FIBRAS (13). EN ALGUNAS FORMAS SE ELIMINA TAL PRESURIZACION.
