Abstract

Procedimiento para la mejora de la tasa de rechazo de membranas de osmosis inversa, agente para la mejora de la tasa de rechazo y membrana de osmosis inversa.#Procedimiento para la mejora de la tasa de rechazo de una membrana RO, que mejora además la estabilidad del rendimiento de la eliminación (tasa de rechazo) y estabilidad del flujo (sostenibilidad de la resistencia a la contaminación). En un procedimiento para la mejora de la tasa de rechazo de una membrana RO, incluyendo una etapa para permitir que una solución acuosa que contiene un polifenol atraviese una membrana RO, el procedimiento comprende además una etapa para permitir que una solución acuosa que contiene, como mínimo, un tipo seleccionado entre el grupo que consiste en un alcohol polivinílico modificado, un polisacárido de alto peso molecular, y un poli(aminoácido) que pase a través de la membrana RO.
