Abstract
Patente de Invenção: <B>"MéTODOS E APARELHO PARA FILTRAçãO APERFEIçOADA DE PARTìCULAS EM SUBMìCRONS"<D>. A invenção em questão refere-se a novos métodos de filtração, novos métodos para a produção de filtros e novos filtros para a filtração eficaz de partículas. Os materiais e métodos da invenção em questão são particularmente vantajosos para a filtração de partículas em submícrons, por exemplo, nanopartículas e podem utilizar a atração elestrostática entre as partículas e as fibras dos filtros microporosos, por exemplo, filtros de polipropileno. Os métodos de filtração em questão podem diminuir a barreira de energia entre as partículas e a superfície do filtro e, assim, aumentar o depósito de particulas sobre a superfície do filtro. Os métodos e aparelho da invenção em questão podem ser usados para filtrar partículas de muitos fluidos, incluindo água e ar. Vantajosamente, os filtros com superfície modificada em questão podem resultar em um fluxo aumentado de fluido, com relação a alguma queda de pressão, comparados aos filtros convencionais.
