A separator (2) for separating solids, such as grit, from an influent, such as water, the tray assembly (4) comprising a plurality of nested tray units (14) which are spaced apart from one another along a vertical separator axis (16). Each tray unit (14) comprises a substantially conical tray (18), an aperture (20) in the apex of the tray (18), and a means for restricting flow through the respective aperture (20), such as a baffle (22) disposed at or adjacent the aperture (20). In use, grit is separated from water circulating among the trays (18) and falls through successive apertures (20) in each of the trays to exit through the bottom of the tray assembly (4). The baffles (22) restrict upward flow through the apertures (20) in the trays (18) thereby reducing agitation of the grit. |
