Abstract

Se proporcionan un procedimiento y aparato para tratamiento de fangos. El procedimiento incluye proporcionar fango en una forma substancialmente líquida y un aditivo alcalino a un recipiente reactor de preferencia substancialmente cerrado, mezclar el fango y aditivo para asegurar que el pH sea mayor que aproximadamente 12, mantener el pH por un período de tiempo predeterminado, aplicar opcionalmente calor suplementario a la mezcla de fango en el recipiente reactor a una temperatura elevada pre-determinada por un período de tiempo predeterminado, mantener la mezcla de fango y aditivo del recipiente reactor en forma substancialmente líquida de manera tal que lleve a manejarlo mediante flujo por gravedad. El aparato proporciona medios para lograr el proceso anterior.
