goals of sludge treatment are:
Stabilization for a controlled degradation of organic
ingredients and odor removal
Volume and weight reduction
Hygiene - the deadening of pathogen organisms
Ameliorating of sewage sludge characteristics for the further
utilization or disposal
The accompanying procedures are used to reach these goals.
The sludge consistency and appearance is changed through treatment.
It must be pointed out that also the heating value of the sludge
changes with the way of the treatment. Anaerobic treated sludge has
a lower heating value than raw sludge because of sewage gas
production. This point has to receive attention by a thermal
