Mercury and VOC Soil Remediation by Ex-Situ Thermal Desorption

Pilot-scale demonstration in Akko, Israel, validating Haemers Technologies' Ex-Situ Thermal Desorption (ESTD) for the treatment of mercury- and VOC-contaminated soils. The project confirmed the technology's ability to achieve residential cleanup targets while ensuring full compliance with atmospheric emission standards.

SITE DESCRIPTION

Treated Volume	275 m³
Thermal technology	Ex-Situ Thermal treatment
Main contaminant	Mercury (HG), VOCs and SVOCs
Site challenges	Former chemical industrial site heavily contaminated with mercury and chlorinated compounds, requiring treatment to residential standards for future redevelopment.
Project Timeline	Jan 2022 - April 2022

SOLUTION

Treatment Method	Ex-Situ Thermal Treatment (ESTT)
Treatment program	Pilot treatment of a 275 m³ soil pile using 15 propane Smart Burners, conductive heating and an integrated vapor treatment system.
Contaminated Vapors Management	Mercury and VOC vapors extracted and treated through a Vapor Treatment Unit (VTU), activated carbon filtration and condensate recovery prior to atmospheric discharge.
Process control	Continuous monitoring of temperature, pile pressure, combustion gases, mercury concentrations and vapor treatment performance throughout the project.
