The increasing amount of treatment sludge must be disposed of with appropriate methods so
that it does not pose an environmental threat. Various methods have been developed and implemented in sludge management for many years.
The methods and approaches applied by EU countries for the final disposal of wastewater treatment sludge vary according to the countries' legal sanctions,
economic and social conditions. There is currently no comprehensive study on the inventory management and final disposal of treatment sludge in Türkiye.
However, it is known that until recently, a large part of treatment sludge was disposed of with the wild storage method. The legal obligations and penal
sanctions introduced in recent years direct treatment sludge producers to dispose of waste in a technical manner without harming the environment.
This also reveals that when Türkiye's current social and economic situation is taken into consideration, a large part of the treatment sludge formed is
disposed of with the regular storage method and some of it is disposed of with the wild storage method in various places. A very small part is disposed
of in cement factories for a fee. For the disposal of the constantly increasing amount of sludge, it is necessary to establish a Sewage Sludge Drying and
Incineration facility. With the established system, the sewage sludge coming out of the decanters will first be increased from the current 27% KM rate to
40% KM rate by means of the drying furnace, and the product will be provided with a 99% KM rate with the fluidized bed boiler. The heat energy required for
the drying furnace is obtained from the sludge burned in the fluidized bed boiler. Finally, by undergoing a heat treatment at a rate of 99% KM, the harmful
pathogens are destroyed, the volume is reduced by 90%, and the product is obtained with an ash content that will not harm the environment. This product will be
disposed of by burying it in the waste storage area at the first stage. In later stages, the product can be evaluated in areas such as asphalt or plastic manufacturing.
The heat to be obtained from the incineration system can be used in electricity production by means of a turbine.
