Feasibility study regarding the in-situ remediation of mercury contaminated soil
Country: Belgium
Start Date:   1/1/2001         Duration: 36 months         Project Type: Feasibility study
Contract Number: 
Organisation Type:  Developer
Topics: 
Contaminated land-->Remediation options-->In situ treatment technologies
Diffuse pollution-->Processes
Soil-->Processes
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
Project Summary: 
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 
iodic complexes.
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.
