Abstract

SE PRESENTA UN METODO PARA SUMINISTRAR MEMBRANAS DE DOBLE CARA (88) UTILES COMO MEMBRANAS DE UN SOLO SENTIDO O MEMBRANAS RECTIFICADORES QUE REDUCEN EL FILTRADO HACIA ATRAS DE LAS MOLECULAS EN SOLUCION EN LA DIALISIS Y QUE MEJORAN EL SUMINISTRO DE NUTRIENTES Y LA RECUPERACION DE PRODUCTOS EN BIORREACTORES DE MEMBRANA. LAS MEMBRANAS SON MATERIALES POLIMERICOS DE DOBLE CARA PREFERIBLEMENTE EN FORMA DE FIBRAS HUECAS. LAS MEMBRANAS TIENEN CARAS (12, 14) DE POLIMERO SOBRE LOS LADOS OPUESTOS CON PERMEABILIDAD DIFERENTE PARA LOS PRODUCTOS EN SOLUCION Y DIFERENTES CARACTERISTICAS DE FILTRADO. LA CARA SOBRE CADA LADO TIENE POROSO QUE SON INVISIBLES A UNA AMPLIFICACION DE 10000 VECES. UNA ESTRUCTURA MICROPOROSA (16) ENTRE LAS CARAS CONTIENE POROS CAPACES DE RETENER PRODUCTOS EN SOLUCION EN UNA BANDA DE PESO MOLECULAR DE ENTRE 5000 Y 200000 EN UNA CONCENTRACION INCREMENTADA ENTRE LAS CARAS INTERIOR (14) Y EXTERIOR (12). SE FORMAN DISPOSITIVOS DE DIALISIS UTILIZANDO MANOJOS DE LAS MEMBRANAS DE FIBRAS HUECAS COMO MIEMBROS DE DIALISIS QUE TIENEN PROPIEDADES RECTIFICADORAS. HACIENDO PASAR REPETIDAMENTE HACIA ATRAS Y HACIA ADELANTE A TRAVES DE LA MEMBRANA (88) EL PRODUCTO EN SOLUCION, ESTE PUEDE SEPARARSE Y CONCENTRARSE SOBRE UN LADO DE LA MEMBRANA (88).
