Abstract

Un método para limpiar y evitar suciedad de difusores de membrana de un sistema de aireación puede incluir: transportar una solución ácida líquida dentro de un tubo descendente o una línea de purga ubicados en un reservorio de un sistema de aireación que contiene un cuerpo de agua tal que la solución ácida líquida fluye dentro de un distribuidor y tuberías de distribución de aire; permitir que la solución ácida líquida se vaporice; y soplar la solución ácida vaporizada dentro de una pluralidad de difusores soportados por las tuberías de distribución de aire. Se incluye también un sistema de aireación que puede implementar el método.
