Abstract
La presente invencion proporciona un nuevo método para desaguar lodos difíciles, tales como lodos de digestion aerobica termofílicos autotérmicos. Elmétodo incorpora un sistema de tratamiento de tres componentes. Inicialmente, el lodo difícil es dosificado con un coagulante inorgánico y luegola mezcla de lodo-compuesto inorgánico resultante es dosificada con un componente en micropartículas. Finalmente, la mezcla resultante es dosificadacon un floculante de alto peso molecular.
