Sludge treatment

The solids removed from the sewage in the course of treatment are rendered harmless by digestion, compostation or pasteurization and then either sintered or incinerated.

Sludge treatment includes:

  • homogenization of sludges (to obtain a conveyable medium)
  • sludge handling
  • sludge dewatering

Classification of conveyed media to DIN 4045


Primary sludge
Sludge from settling tanks
Secondary sludge
Sludge from biological treatment
Tertiary sludge
Sludge from advanced sewage treatment
Mixed sludge
Any combination of the above
External sludge
Sludge hauled to the sewage treatment plant from other sources

Pumps and valves by KSB for any and all jobs


Amamix submersible mixers do an excellent job homogenizing tank contents in the sludge treatment stage.
