Abstract

La presente invención se refiere a un estabilizador para un lodo que tiene un contenido de sólidos en el rango de aproximadamente 3 a 8 por ciento del contenido de sólidos secos, caracterizado porque comprende al menos un tanque reactor hueco que tiene una entrada y una salida para el lodo, medios para controlar el flujo del lodo a través del tanque de manera que el tanque se llena sustancialmente con el lodo a una presión hiperbárica, medios para introducir burbujas microscópicasde oxígeno y / o gas ozono en el lodo dentro del tanque, un mezclador montado dentro del tanque que hace que las burbujas de gas se pongan en contacto con el lodo, el mezclador estando montado y configurado con respecto al interior del tanque de manera que el lodo se pone en contacto por el mezclador con cualquier acumulación de gas en la porción interior superior del tanque, y medios para impulsar el mezclador.
