Feasibility study regarding the in-situ remediation of mercury contaminated soil
| Country: Belgium
| Start Date:
Project Type: Feasibility study
| Contract Number:
| Organisation Type:
Contaminated land-->Remediation options-->In situ treatment technologies
| Project objectives:
Phase 1: Engineering of process installation
Phase 2: Construction of process installation
Phase 3: Characterisation of contaminated test site (8 x 12 m)
Phase 4: Remediation
Phase 5: Characterisation of cleaned site and evaluation of feasibility of remediation technique
The feasibility of a new in-situ remediation technique was tested. The remediation technique makes use of the principles of electro remediation, combined
with the use of iodic complexants to solubilize the mercury from the soil, and solvent extraction to isolate the recovered mercury from the waste solutions.
The complexants are introduced into the soil by means of an electric field (electroremediation). This field is also used to remove the solubilized (ionic)
mercury complexes from the soil. Soil electrodes are flushed with process solution, which is treated above the ground to isolate the mercury and to reuse the
| Achieved Objectives:
The objectives of phase 1, 2 and 3 were achieved. The project was stopped during the execution of phase 4/5. It became clear that the technique could never be economical
feasible, because of the introduction of some needed extra process steps.
