Solid Liquid Extraction Unit.
Solid Liquid Extraction Unit Contaminants may be present sorbed in the solid particles of the soil.
Solid-liquid extraction allows these contaminants to be removed from the
soil.
Depending on the contaminant and the type of soil, a suitable
solvent needs to be selected for this process. One field of application
for example, is the separation of organic contaminants that are present
sorbed in fine solid particles. Solid-liquid extraction may take place
after these fine particles have been separated by a hydrocyclone in the
ex-situ treatment of contaminated soil. The fundamental principle of
solid-liquid extraction can be learned with the CE 630. The temperature
of the solvent can be adjusted. Thus, it is possible to investigate the
effect of this parameter on the separation process.
