Modular Soil Washing and Remediation Plant

Soil washing, also named as soil leaching,  is an ex-situ remediation technique that removes hazardous contaminants from soil. It can significantly reduces the volume of contaminated soil at site.

Desen has developed the advanced compact modular soil washing and remediation plant suitable for physical and chemical washing and remediation of contaminated soils and industrial sites such as chemical, pharmaceutical, metallurgical, petrochemical, and mining areas. It realizes the efficient treatment for hexavalent chromium, lead, cadmium, zinc, arsenic, and other heavy (non-)metals (excluding Hg), semi-VOCS, PCBs, PHCs, and other single or combined contaminated soils.

Technical Principles

Desens modular washing and remediation solution is to promote the dissolution and migration of contaminants in the soil through a series of physical and chemical comprehensive treatment processes.

Application effects after treatment

High washing/leaching efficiency, high heavy metal removal rate ;
 
 (The data gathered from our client sites show that the total amount of heavy metal pollution factors in the soil and the water leaching concentration indicators have been effectively reduced.)
 
The reduction rate of polluted soil is over to *0%;
 
The sand and stone aggregate in the soil can be recycled after being washed and classified;
 
 The pressed mud cakes can be used for safe backfilling if tested qualified；
