Abstract

Un procedimiento para limpiar impurezas en partículas de un lecho de resinas de cambio iónico en un recipiente de filtración, que comprende: ajustar el nivel de líquido en el interior de dicho recipiente a un punto intermedio situado entre la parte superior de dicho recipiente y la superficie superior de dicho lecho, proporcionando una zona libre dentro de dicho recipiente; introducir un gas en dicho recipiente en un nivel situado por debajo de la superficie superior de dicho lecho de resina pero por encima de una porción del mismo sustancialmente inferior, desprendiendo con ello de la resina dichas impurezas en partículas por encima de dicho nivel de introducción de gas y suspendiendo dichas impurezas en dicho líquido; recoger dicho gas en dicha zona libre de dicho recipiente y terminar dicha introducción de gas al alcanzarse una presión previamente determinada en dicho recipiente; y retirar de dicho recipiente una porción de dicho líquido que contiene dichas impurezas suspendidas a un nivel igual por lo general a dicho nivel de introducción de gas.
