Abstract
"MEIOS DE FILTRAçãO, E, PROCESSOS DE FILTRAçãO E DE FABRICAçãO DE MEIOS DE FILTRAçãO" Meios de filtração tendo pelo menos uma camada polimérica estruturada, em que a superfície estruturada está definida dentro da camada. As camadas podem ser configuradas como uma pilha que tem as superfícies estruturadas definindo uma pluralidade de aberturas de entradas ordenadas através de uma face da pilha e os caminhos de fluido ordenados correspondentes, desse modo formando um volume poroso ordenado. Os caminhos de fluido ordenado podem ser definidos através de uma pluralidade de canais de fluxo formados dentro das superfícies estruturadas das camadas estruturadas, ou podem ser definidos através de uma pluralidade de protuberâncias formadas em um modelo ordenado dentro das superfícies estruturadas das camadas estruturadas.
