Abstract

"MEIO FILTRANTE COM RETENçãO GRADUADA DETAMANHO DE PARTìCULA PARA UNIDADE FILTRANTE ECARTUCHO DE FILTRO DO TIPO DE CéLULA". Provê-se umaunidade filtrante do tipo de célula possuindo duas ou maiscamadas e/ou zonas de meios filtrantes, pelo menos uma dascamadas/zonas que possui uma capacidade de retenção departícula diferente sendo disposta em cada lado de um elementoseparador não filtrante. Os meios filtrantes são preferivelmenteposicionados de modo tal que cada camada ou zona filtrantesucessivamente distal do separador possui uma capacidade deretenção de partícula menor que cada camada ou zona filtranteantecedente. A camada de meio filtrante mais proximal ao elementoseparador pode ser separada do separador por um material desustentação, a fim de sustentar tal elemento de meio filtrante eevitar o desmoronamento dos meios dentro de qualquer condutoseparador.
