<p>The present invention relates to a process for converting a substantial wet sludge into dried pellets comprising: - bringing the wet sludge into a rolling contact over at least one heated plate, - indirect drying of said rolled wet sludge by a conductive heat transfer from the heated plates to the sludge, and - simultaneously pelletizing the heated sludge which process is performed under an inert atmosphere in order to minimize the explosions and/or combustion risks. The invention further relates to an apparatus for the treatment of sludge into pellets.</p> |
