The majority of heavy metals generated by Waste Incineration or Coal Firing condense on Fly Ash or Spray Drying products and are removed from the gas stream in the particulate collector.

Mercury, however, may remain as a vapor through out the Scrubbing process. To control Mercury emission, Clyde Bergemann EEC UK (CBEECUK) provides activated carbon and other reagent-based mercury removal systems.

The reagent is injected into the ductwork or introduced into the process through the Spray Dryer. Mercury is absorbed by the reagent and subsequently removed by the particulate removal device.
