Abstract

Se proveen un procedimiento para destruir ácido formico y/o formaldehído en una corriente de desecho acuosa, de ácido orgánico, poniendo en contacto la corriente con un catalizador en soportado de metal precioso y haciendo pasar gas aire u oxigeno molecular a través de la solucion para promover la oxidacion química; la invencion es una alternativa segura, práctica u eficaz en cuanto a costo para el tratamiento en biosistema de estos compuestos usando microorganismos; el procedimiento de la invencion puede practicarse de manera ya sea intermitente o continua y, de acuerdo con la invencion del ácido formico presente en una corriente a un nivel de 3800 ppm y el formaldehído presente en una cantidad de 5,800 ppm pueden reducirse respectivamente a niveles de 200 ppm o menos.
