Municipal solid waste wet seperation process

摘要

An apparatus (2) for separating and processing the components of Municipal Solid Waste (MSW) is described. Shredded MSW is fed into a first separator means (8) comprising a cylindrical container portion (10) in which auger means (12) is disposed. The auger means generally acts as an Archimedes screw and comprises a plurality of blades (14) disposed around the inner circumference of the barrel (10). The waste fed into first separator means (8) is mixed with water and the barrel (10) rotated. Solid waste of higher density tends to be spun under a centrifugal force towards the wall of barrel (10) and is moved upwardly by the blades (14) to a first outlet (14), Solid waste of lower densities mixed with water tends to flow downwardly towards second outlet (16).
