Abstract
LA INVENCION SE REFIERE A UN PROCEDIMIENTO DE LIMPIEZA DE LAS INSTALACIONES DE FILTRADO QUE VAN PROVISTAS DE VARIAS MEMBRANAS SUMERGIDAS EN AL MENOS UNA CUBA QUE CONTIENE EL EFLUENTE QUE VA A FILTRARSE. EL PROCEDIMIENTO COMPRENDE LAS SIGUIENTES ETAPAS: DESAGUAR AL MENOS EN PARTE EL EFLUENTE DE LA CUBA, DE FORMA QUE LAS MEMBRANAS QUEDEN EXPUESTAS AL AIRE; PASAR AL MENOS UNA SOLUCION DE LIMPIEZA A TRAVES DE DICHAS MEMBRANAS MEDIANTE UN FLUJO INVERSO AL FLUJO DE FILTRADO DEL EFLUENTE DIRIGIENDO LA SOLUCION DE LIMPIEZA POR EL LADO PERMEADO DE LAS MEMBRANAS.
