A process of treatment of carbonaceous material, such as wastewater sludge or organic waste, includes performing a thermal treatment of the carbonaceous material, thereby providing thermally treated carbonaceous material, cooling the thermally treated carbonaceous material, thereby providing cooled carbonaceous material, the cooling being performed using a vacuum cooling procedure, and performing a post-treatment of the cooled carbonaceous material, and at least one carbonaceous material degassing.

There is provided a system for sludge treatment, which system is arranged in a container adapted to be transported by a truck and comprises: a sludge inlet for receiving a sludge; a reactor comprising an electrical heating arrangement for heat treatment of the sludge, which reactor is arranged downstream the sludge inlet; a flashing arrangement for cooling sludge treated in the reactor and providing at least one steam fraction, which flashing arrangement is arranged downstream the reactor; a steam routing arrangement capable of routing the at least one steam fraction from the flashing arrangement to preheat sludge transported from the sludge inlet to the reactor; and a separation arrangement for separating the cooled sludge from the flashing arrangement into a first fraction and a second fraction, wherein the suspended solids content is higher in the first fraction than in the second fraction. A corresponding method is also provided.

The present invention provides a drying apparatus. The apparatus includes a first, upper chamber comprising a freezing section; and a second, lower chamber comprising a thawing section and a drying section. The first, upper chamber further includes an inlet and first conveying means arranged to convey material through and within the freezing section. The second lower chamber includes second conveying means arranged to convey material through and within the thawing section, and third conveying means arranged to convey material through and within the drying section. A first outlet is provided in the drying section through which dried material exits the apparatus. Generally, the material provided to be dried by the drying apparatus is alum sludge.
