Abstract
"MEIO DE FILTRO COMPóSITO, MéTODO DE REMOVER CONTAMINANTES MICROBIOLóGICOS EM UM FLUIDO E SISTEMA DE FILTRO". A presente invenção é dirigida a um meio de filtro compósito tendo um material que altera o pH que pode elevar o pH de um afluente de tal modo que contaminantes microbiológicos no afluente permanecem carregados de modo substancialmente negativo de maneira tal que um meio positivamente carregado dentro do meio de filtro compósito pode capturar mais efetivamente os contaminantes microbiológicos.
