New Objectives of Sludge Treatment Considering a Safe Sludge Removal

Sewage Sludge consists of valuable compounds such as nutrients as well as harmful substances e.g. heavy metals. For sludges with a low pollutant concentration, utilization in agriculture is the best option for sludge reuse.

by Prof. Dr.-Ing. Norbert Dichtl

Highly polluted sludges are not suitable for agricultural reuse, but carbon recycling is possible by using mechanical (disintegration) or chemical pre-treatment with anaerobic degradation processes. The other important valuable compound in sludge is phosphorus which is a limited resource on earth. Recycling options for phosphorus are also describe in the paper. A safe disposal of the residues can be achieved by using incineration.
