Apparatus for removing grit and fiber from waste activated sewage sludge prior to introduction into a centrifuge for further separation. Grit removal is accomplished by hydrocyclones and fiber removal is carried out on a 300 DEG screen. The hydrocyclones and screen, together with connecting conduits, are conveniently mounted on a supporting frame for facilitating transportation of the unit and for maintaining the predetermined structural relationships of the various members. |
