Air and gas purification

Purification of biogenic and technical gases

Unwanted trace gases are often the cause of expensive damage in technical facilities, are toxic and also have an environmental impact too. Thanks to our experience and technical knowledge, we are on hand to help you remove these trace gases from all kinds of biogenic and technical gas streams.

  • Purification of technical gases
  • Purification of biogas
  • Purification of sewage treatment gas
  • Purification of landfill gas
  • Solvent recovery
  • Soil air purification
  • Exhaust air purification
  • Odour removal
