Electro (Bio) Reclamation
Where chemical, biological or physical techniques fail (for example by loamy or clayey soil) heating can be the solution. Verhoeve Environment & Water has the know-how, patents and equipment for heating of the soil under the influence of alternating current. By placing electrodes with a power unit, heat can be generated in the soil. The warming of the soil increases the biological activity extremely. In addition, the permeability of the soil increases and persistent adsorbed contaminants detach from the soil matrix. Deployment of electro(bio)reclamation guarantees a rapid settlement of the soil and prevents stagnation of the remediation.

The technique is often combined with biological aftertreatment and / or physical techniques such as multi-phase extraction or soil vapor extraction. It is also possible to make a combination with compressed air injection and / or injection of nutrients. The temperature of the soil can reach up to about 90 gr. C. in the intensive phase for treatment of source zones or DNAPL.
Application:
- Heating or in situ remediation of highly clayey or peaty soils;
- Increase solubility of chlorinated solvents, mineral oil or PAH compounds;
- Approach of saturated and unsaturated zone of source zones by heating.
