Abstract

Dispositivo para la distribución del agua sobre un filtro con relleno de materiales granulares y para la recuperación del agua de lavado de dicho filtro durante la fase de desobstrucción de éste con agua y aire, consistente en un canalón adosado al filtro en toda su longitud y cae se abre hacia el mismo mediante un desaguadero configurado a iodo de deflector por dos planos inclinados en sentido inverso que forman un pico hacia el interior del filtro, caracterizado porque dicho canalón está cerrado en su parte superior y mantenido a presión hidrostática durante la fase de desobstrucción del filtro con agua y aire.
