Natural Occurring Radioactive Material consists of materials enriched with radioactive elements found in the environment. They are usually brought to the surface by oil and gas exploration or mining. NORM wastes can be treated in a VacuDry® unit in order to prepare it for a safe sub earth disposal.

Benefits of VacuDry® NORM waste plants:

  • Environmentally friendly separation of oil, mercury and water from NORM waste (required for final safe disposal)
  • Separately recovered contaminants by fractional condensation
  • High temperatures and low vacuum ensure a thorough cleaning process
  • Low energy consumption ensured through controlled power requirements
  • Emission and dust-free system; encapsulated treatment of exhaust vapours and solids
