What is the volume reduction percentage when sludge is incinerated?

The volume reduction percentage when sludge is incinerated typically falls within the range of 80-90%. This high percentage is attributed to the combustion process, where organic materials in the sludge are completely burned away, resulting in the formation of ash and gases. The remaining ash forms a small residual volume compared to the original sludge, leading to a significant decrease in volume.

This process is beneficial for managing waste materials, as it not only decreases the volume needing disposal but can also potentially generate energy through the incineration of combustible components. The efficiency of incineration in achieving this level of volume reduction underscores its effectiveness as a sludge management technique in wastewater treatment facilities.
