Abstract

"FILTRO PARA OBTENçãO DE áGUA POTáVEL E PROCESSO PARA OBTENçãO DA REFERIDA áGUA". A invenção refere-se a um filtro para a obtenção de água potável. O filtro inclui um envoltório com uma entrada e uma saída, um material filtrante disposto dentro do envoltório, que é formado, pelo menos em parte, a partir de uma pluralidade de partículas filtrantes. As partículas filtrantes têm um ponto de carga zero superior a 7, e a soma dos volumes dos mesoporos e macroporos da pluralidade de partículas filtrantes é superior a 0,12 mL/g.
