Abstract
"SISTEMA DE DRENO SUBTERRâNEO DE FILTRO PARA FLUXO PARA LAVAR POR CORRENTE DE áGUA LIMPA E MéTODO PARA MEDIR O MESMO". Trata-se de um sistema de dreno subterrâneo de filtro e um método para medir o fluxo de água através do sistema de filtro de dreno subterrâneo. O aparelho inclui elementos de painel montados para formar um retículo perfurado na estrutura de base do filtro de um bloco de dreno subterrâneo. Os painéis são geralmente retangulares e possuem uma superfície inferior e superior. Aberturas múltiplas são providas no elemento de painel. O número e/ou dimensão de aberturas são dimensionadas para impedir o egresso de mídia de filtro e para obter fluxo para lavar por corrente de água limpa substancialmente uniforme no dreno subterrâneo desse modo reduzindo ou eliminando a má distribuição de água.
