Abstract

"MEMBRANAS MICROPOROSAS PARA DESSALINIZAçãO DE áGUAS". O presente relatório descritivo da patente de invenção refere-se ao desenvolvimento de uma formulação química de tiras de membranas microporosas obtidas por fotoreticulação de resina epoxi-diacrilato suportadas em papel celulósico para osmose reversa, as quais, devidamente adequadas através de design e engenharia otimizam a performance dos módulos dos sistemas conjugados de membranas para processo de separação de alto fluxo com alta taxa de rejeição de sal.
