  • Separator
    Patent number: 4451366
    Abstract: A separator and a method for separating putrescent solids from water in sewage. A vortex chamber (2) has an inlet (for the sewage), a first (solids) outlet (6) and a second (water) outlet (8). Near the outlet (6) there is a flow modifying member (14) which induces a secondary flow in the vortex chamber (2). A portion of this secondary flow passes radially inwardly beneath the member (14) and upwardly through a passage (18). The member (14), if suitably shaped and dimensioned, improves the efficiency of the separator.
