Thermal Sludge and Soil Treatment

Decontamination of soil from flammable or volatile substances

In a first step, the polluted soil is heated up. This leads to a degassing of the soil. Direct lighting is possible as well as indirect lighting. During the second step, the into gas phase transferred contamination stream is subsequently burnt at a higher temperature. Through the heating of the soil, natural soil contents could be destroved. However, this biologically dead substrate can be recycled with the help of organic matter.

Residual products from the exhaust air treatment need to be disposed.

Next th methods which work with a high temperature scale from 300°-1,200°C, low-temperature processes (<300°C) can also be used:
  • Thermal Desorption
  • Vacuum Distillation
  • Steam Distillation
