SOLID-SOLID EXTRACTION APPARATUS

Product Description

Contaminants may be presentsorbed in the solid particles of the soil. Solid-liquid extraction allows thesecontaminants to be removed from the soil. Depending on the contaminant and thetype of soil, a suitable solvent needs to be selected for this process.

One field of application forexample, is the separation of organic contaminants that are present sorbed infine solid particles. Solid-liquid extraction may take place after these fineparticles have been separated by a hydrocyclone in the ex-situ treatment ofcontaminated soil. The fundamental principle of solid-liquid extraction can belearned with the temperature of the solvent can be adjusted. Thus, it ispossible to investigate the effect of this parameter on the separation process.
