Decontamination of Soils


Decontamination of soils with organic compounds

RYMOIL use thermal desorption in this kind of contaminated soils.

RYMOIL, S.A. has a list of regulatory documents available to our customers. If you want to consult any of them, you can request it by email

Thermal Desorption Process

Consists of soil cleaning by volatilization of organic pollutants that affect the soil. This treatment system consists of two stages:

  • Stage 1: Transfer of the organic pollution from the ground into the gas phase.
  • Stage 2: Destruction of pollution contained within the gas phase.

This technique is used for decontamination "in situ" of soils polluted with organic compounds and whose volume of soil is important.

Soil Washing Process

Soil washing is a mechanical process that uses liquids, usually water, to remove chemical pollutants from soils. Therefore, the purpose of soil washing is to first, separate the fine silt and clay particles from the coarser sand and gravel particles and then to facilitate the transfer of these chemical contaminants from the soil surface to the water, which can then be further treated by other process.

With this technique the hazardous pollutants tend to join either chemical or physical to the silt and clay.

The coarse fraction (highest volume) is not contaminated and can be used as fill on-site.

This technique can be used in soils affected by a wide variety of products such as fuels, metals, and pesticides.
