Separation of mercury from contaminated soils

Our client, faced with mercury contaminated soil from a former thermometer factory in India, enlisted econ industries to create a soil recycling facility. The goal was to address the remediation of mercury contaminated soil on-site through ex-situ remediation, avoiding the challenges of transporting hazardous material over long distances. To comply with local transport restrictions, limiting skids to 20 ft. and 20 tons, econ proposed their semi-mobile VacuDry® 3 000. In 2020, the fully assembled plant was successfully delivered to India. Despite the global pandemic and stringent health and security measures, econ’s engineers efficiently oversaw the entire assembly, commissioning, and local personnel training in early 2021.

Design characteristics

  • Modular design – reduced transport costs, fast and efficient installation
  • Working in batch-mode – highest flexibility to treat every mercury waste stream
  • Low tear and wear compared to other systems – due to robust and slow moving agitator
  • Perfect control of the process – due to online monitored batch process
  • Highest safety level – (CE and ATEX certified)
