Abstract

Un bloque de desagüe inferior para filtrar agua que consta de una pared superior, una pared inferior y dos paredes laterales que conectan la pared superior con la pared inferior para crear una cámara interior. La pared inferior posee varios orificios que permiten que los materiales líquidos y sólidos entren y salgan de la cámara interior. Se puede conformar un sistema de filtrado del desagüe inferior al fijar un lateral de desagüe inferior, que consta de uno o más bloques de desagüe inferiores, a un suelo filtrante. También se incluye un método para establecer un lateral de desagüe inferior que proporcione una distribución uniforme del agua de retrolavado a lo largo del lateral de desagüe inferior y un método para validar la distribución uniforme del agua de retrolavado a lo largo del lateral del desagüe inferior.
