Home > Sludge treatment > Incineration
The sludge is generally dewatered to a high solid content to make it more suitable for incineration. The sludge cakes are then fed into a fluidized bed incinerator and incinerated at a temperature of 850°C. Energy can be recovered through a number of heat exchangers used to dissipate heat from the incineration to other heat requiring steps in the process. One of the problems is that the gases released into the atmosphere are perceived as being potentially hazardous.
