Abstract

Un arreglo sin marco ilimitado en una capa modular, prueba que es un dispositivo de membrana sorpresivamente efectivo para retirar el permeado de un substrato, el flujo a través de las membranas alcanza un valor relativamente alto esencialmente constante debido al despliegue crítico de fibras del arreglo como madeja, arqueándose en una configuración generalmente parabólica boyantemente oscilante dentro del substrato, arriba de al menos uno de los colectores del arreglo en el que se condensan las porciones extremas terminales de las fibras. La longitud de cada fibra debe ser más grande que la distancia directa de centro a centro entre el par de colectores del arreglo. Para uso en un dispositivo grande, un ensamble del arreglo y unos medios distribuidores de gas tienen fibras de preferencia de mas de 0.5 metros de largo, que juntas proporcionan una área superficial de más de 10 metros cuadrados. Las porciones extremas terminales de las fibras en cada colector están substancialmente libres de contacto fibra a fibra. Cuando se usa en un tanque desde el cual se retira el permeado en un lugar lo suficientemente bajo como para superar la diferencial de presión de la transmembrana de las fibras, el permeado se retira bajo un vacío inducido por gravedad. Para incrementar el flujo, se puede usar una bomba que proporciona una succión de menos de 75cm de mercurio. Cuando se usa en combinación con un distribuidor de distribución de gas dispuesto debajo de la madeja para hacer fluir burbujas a través de él, las superficies de las fibras son sorprendentemente resistentes a ser obstruidas por la acumulación de depósitos de partículas inanimadas o microorganismos en el substrato. Se pueden usar membranas con una alta diferencial de presión de la transmembrana, si se desea, y remover el permeado con una bomba de vacío.
