Device and method for the treatment of FORSU

A device for the treatment of FORSU (Organic a Fraction of Municipal Solid Waste), comprising first module for the formation of a heterogeneous mixture of FORSU mounted above a second module for homogenizing the heterogeneous mixture of FORSU, wherein

• the first module comprises a longitudinal vat containing a first auger, a cylindrical filter that surrounds a second auger, the cylindrical filter being housed with an interspace in a vertical casing, the FORSU being conveyed from the longitudinal vat to the cylindrical filter,
• the vertical casing further comprises a tubular fitting for introducing the FORSU from the longitudinal vat to the cylindrical filter through a first opening provided at a lower end of the cylindrical filter, a plurality of nozzles for directing a liquid for diluting the FORSU on the cylindrical filter, and a second opening at an upper end for the discharge of coarse inserts,
• the second module comprises a first chamber, a second chamber and a third chamber,
• the first chamber is arranged below the cylindrical filter, the heterogeneous mixture of FORSU coming through the lower end of said cylindrical filter falls directly into the first chamber due to gravity,
• the first chamber contains a mixture and removal auger and a third auger for transfer and removal of residue inerts,
• the first chamber is followed by the second chamber having a greater longitudinal extension than the first chamber, and into which the third auger extends from the first chamber for conveying and removing finest inerts towards an external,
• the first chamber and the second chamber are in fluid communication with each other through a connection opening positioned on a separating wall between the first chamber and the second chamber, and
• the second chamber is followed by the third chamber for further mixing the matrix in the mixture in a substantially liquid state, and discharging the mixture through a discharge end, wherein between the second chamber and the third chamber there is provided an overflow opening,
• the connection opening has a lower height than that of the overflow opening, and
• the first chamber and the second chamber have a same level of liquid due to the overflow opening.
