Denitrification Filters

Deep-bed denitrification filter

The deep-bed denitrification filter is a treatment unit which combines the functions of biological denitrification and filtration. The ceramic filter media with special size and shape is applied as the media for the growth of bio-film, which makes the filter equipped with the functions of nitrate, ss and total phosphorous removal.

Deep bed denitrification filter

Main advantages:

  • The denitrification and chemcial phosphorous removal can be achieved simultanously
  • Investment on civilwork and installation can be reduced; sturdy and durable
  • The air-water-distribution filter block for denitrification filter is applied to achieve excelloent air-water-distribution performance during backwashing
  • The sizing of the filter can adapt to a wide range of scenarios and is eligable to newly-built and renovation projects
  • The precise auocontrol can be achieved to get the excellent water quality of effluent with a lowest dosing quantity
  • Under the condition that carbon sources are abundant: TN (inlet) <15

Main applications:

  • Effluent quality upgrade for municipal sewage treatment
  • Effluent quality upgrade for industrial wastewater treatment
  • Advanced treatment for existing plants
