A separator (100) of solid substances for the treatment of sewage sludge, the separator comprising an auger conveyor (101) presenting a shaft (105) that is axially fixed and freely rotating within a first filtering station (118) comprising a filtration chamber (103), cylindrical and coaxial to the shaft (105); a helical member (106) being carried coaxially by the shaft (105) in order to transport the sludge along a path (128) extending between an inlet conduit (102) and a discharge chamber (104) of the filtration chamber (103); the shaft (105) presenting a first, substantially conical, coaxial portion (108) whose diameter increases along the path (128) to compress the sludge in an increasing manner along the path (128) in order to increase the quantity of solid substances contained in the sludge per volume unit. |
