Abstract

"ELEMENTO DE FILTRAçãO QUE APRESENTA UMA PAREDE LATERAL DE DENSIDADE VARIáVEL". A presente invenção refere-se a um elemento de filtração que é formado de componentes ou filamentos fibrosos sobrepostos. Aqueles filamentos fibrosos no lado do elemento de filtração que primeiramente recebe o fluxo de líquido tendo uma espessura e aqueles filamentos fibrosos no lado do elemento de filtração de onde o fluxo de líquido sai tendo uma espessura substancialmente menor do que a espessura dos filamentos na parede lateral oposta do elemento.
