Abstract

EL FLUJO DE UNA MEMBRANA DE COMPOSITE PARA NANOFILTRADO U OSMOSIS INVERSA CON UNA CAPA DISCRIMINANTE DE POLIAMIDA SE AUMENTA EN UN PROCESO DE UN SOLO PASO EN EL QUE LA CAPA DISCRIMINANTE SE TRATA CON AMONIACO O CIERTAS ALQUILAMINAS. ES POSIBLE CONTROLAR TANTO LA TASA DE RECHAZO COMO EL FLUJO DE LA MEMBRANA, ASI COMO CONVERTIR MEMBRANAS DE OSMOSIS INVERSA EN MEMBRANAS DE NANOFILTRADO.
