Abstract
A fine solids separator 10 including a hollow housing 12 having a generally cylindrical wall 11. Located within the housing 12 is a cylindrical screen member 15 that is preferably formed of expanded metal mesh. The screen member 15 encloses a chamber 22 to which a flocculated sewage is delivered by means of an inlet duct 23. Located within the chamber 22 is an impeller 26 which at least aids circulation of liquid within the chamber 22 about the longitudinal axis of the chamber 22. Liquid leaves the chamber 22 via the screen member 15 and an outlet 25 extending from an outlet chamber 24 located between the member 15 and housing 12.
Claims29
An apparatus to remove solid material from a body of liquid, said apparatus including:
- a generally cylindrical wall providing a chamber to receive the liquid, said cylindrical wall having a generally vertical longitudinal axis and including an apertured portion through which the liquid leaves the chamber, the apertured portion being adapted to remove solid material greater than a predetermined size from liquid passing through the apertured portion, and wherein said wall is mounted for rotation about said axis;
- a housing generally surrounding said wall and co-operating therewith to provide a space into which the liquid flows from said apertured portion;
- liquid drive means to at least partly cause movement of the liquid in the chamber about said axis so that liquid passes the apertured portion to aid in removing solid material therefrom;
- a motor to cause said rotation;
- means to remove the solid material from within the chamber;
- an inlet via which liquid is delivered to said chamber;
- and
- an outlet extending from said space so as to maintain a level of liquid in said space and chamber.

- a housing generally surrounding said wall and co-operating therewith to provide a space into which the liquid flows from said apertured portion;
- liquid drive means to at least partly cause movement of the liquid in the chamber angularly about said axis so that liquid passes the apertured portion to aid in removing solid material therefrom;
- means to remove the solid material from within the chamber;
- an inlet via which liquid is delivered to said chamber, said inlet being spaced from said axis so as to direct the liquid to move angularly about said axis, with the liquid drive means augmenting said angular movement;
- and
- an outlet extending from said space so as to maintain a level of liquid in said space and chamber.
