Abstract

membrana compósita para nanofiltração, uso de uma membrana, e, processo de polimerização interfacial para formar uma membrana compósita para nanofiltração por solvente. a presente invenção refere-se a uma membrana compósita para nanofiltração de uma solução de corrente de alimentação compreendendo um solvente e solutos dissolvidos e motrando rejeição preferencial dos solutos. a membrana compósito compreende uma película polimérica fina formada por polimerização interfacial sobre uma membrana de suporte. a membrana de suporte é ainda impregnada com um agente de condicionamento e é estável em solventes apróticos polares. a membrana compósita é opcionalmente tratada em um meio de desativação, em que a reação de polimerização interfacial pode ser desativada e, em algumas formas de realização, a química da membrana pode ser modificada. finalmente, a membrana compósita é tratada com um solvente ativador antes da nanofiltração.
