TLDR
In this paper, the authors proposed a three-stage system in which excess sludge from a high loaded activated sludge plant is used as carbon source and as source of denitrifiers.About:

Performance of double-layer biofilter packed with coal fly ash ceramic granules in treating highly polluted river water.
TL;DR: To improve trickling filters' denitrification efficiency, a biofilter with a trickling upper layer and a submerged lower layer was developed and applied in treating highly polluted river water and indicated this biofilter was started quickly with river sediment as inoculum.
Removal Of Refractory Tkn From An Effluent Wastewater Using Sodium Ferrate
TL;DR: In this paper, Ferrate, a strong oxidant, was used for the treatment of these nitrogen forms with the objective of producing nitrogen compounds that can be removed by subsequent biological processes.
Denitrification in fixed film domestic wastewater treatment systems without an additional carbon source - A modeling approach
TL;DR: In this paper, a literature survey and mathematical modelling of three different trickling filter configurations was performed to determine the best system for denitrification in fixed film domestic wastewater treatment systems without an external carbon source.

Post-Denitrification with Controlled Feeding of Activated Sludge as H Donator
I. Sekoulov,R. Addicks,J. Oles +2 more
TL;DR: In this article, a system using thickened sludge from the activated sludge sedimentation as H donator was proposed to denitrify the trickling filter effluent.
