Abstract

El invento se refiere a un método para limpiar una instalacion de filtrado del tipo constituido por una pluralidad de membranas sumergidas en un tanque por lo menos, que contiene un efluente que va a ser filtrado, caracterizándose dicho método porque incluye los pasos consistentes en: - drenar por lo menos parcialmente el efluente contenido en dicho tanque de manera que se expongan al aire dichas membranas; - hacer pasar por lo menos una solucion de limpieza a través de dichas membranas a lo largo de un trayecto de flujo en sentido opuesto al flujo de filtrado del efluente, alimentando dicha solucion de limpieza desde el lado permeado de dichas membranas.
