Thermal Treatment via VTD

Perma-Fix II (VTD) Perma-Fix offers a thermal desorption process which is used to remove the free organic fraction from inorganic solids that contain volatile or semi-volatiles. This process uses a combination of temperature (up to 625°F), vacuum and carrier gases (e.g. steam & inert gases) to aid in the separation and desorption. This process is performed in an oxygen free environment. The desorbed constituents are then treated via direct chemical oxidation or combustion. In some cases, this desorption process can also be used as a destruction process. Once thermally desorbed the waste could require stabilization to render it amenable for disposal. The secondary liquids generated through this process are thermally destroyed via combustion at our DSSI facility.
