Here is your answer,

======================================================

Sludge is a semi-solid slurry that can be produced from a range of industrial processes, from water treatment, wastewater treatment or on-site sanitation systems.

The amount of sewage sludge produced from the activated sludge process is directly proportional to the amount of wastewater treated.

The total sludge production consists of the sum of primary sludge from the primary sedimentation tanks as well as waste activated sludge from the bioreactors.
