Abstract

Solid-liquid separation procedure in the treatment of residual organic sludge, characterized in that it comprises the steps of adding 0.5 to 30% by weight of hydrogen peroxide and 0.1 to 10% by weight of an ion to the sludge. metallic with trivalent positive charge or higher valence, with respect to the solids content of the mud, while maintaining the pH at or below 9 by addition of an acid or alkali, to form stable organic flocs; and then carry out a centrifugal separation.
