Hazardous Waste Destruction

General Atomics Electromagnetic Systems (GA-EMS) industrial Supercritical Water Oxidation (iSCWO) technology is successfully treating a broad range of pumpable hazardous and non-hazardous waste, with a 99.99% destruction removal efficiency.  iSCWO provides a safe, cost effective, and environmentally sound solution to replace alternative technologies that have high emission rates, post treatment requirements, and substantial installation and operation costs. 

Safe, effective destruction of

  • Expired or obsolete pesticides, fertilizers and fungicides
  • Contaminated water (waste water clean up)
  • Expired or obsolete paints and/or petroleum products
  • Petroleum waste streams
  • Organic cleaning solutions
  • Energetic material (explosives or propellant)
  • Unique material not suitable for normal transportation or disposal

Fixed and Transportable Solutions

In addition to offering fixed site solutions, GA-EMS provides the only flexible, transportable iSCWO system available today to facilitate "generate and destroy on-site" capabilities.  The modular design allows for rapid set-up and start of process operations.  A single three gallons per minute (3 GPM) transportable system consists of two compact equipment skids housed inside two shipping containers to create a convenient, cost effective platform for multiple site waste destruction when and where it is needed.  Parallel, redundant system designs are available for both fixed and transportable systems to increase throughput and improve efficiency.

iSCWO - How It Works

GA-EMS'  iSCWO system makes use of the unique properties of water at conditions above its thermodynamic critical point.  The system creates supercritical conditions which render organic materials, oxidation reactants, and oxidation products miscible in water, allowing complete oxidation to take place at a high rate. The result of this high temperature, high pressure process is the breakdown of the waste into carbon dioxide, water and salts, all of which can be released into the environment or reused for other industrial purposes without any post treatment.
