TLDR
3D-BER is a feasible and effective technology for the denitrification of WWTP effluent with poor organic carbon source and the extension of hydraulic retention time (HRT) could enhance nitrate removal, but too long HRT was not necessary.About:

Effect of salinity on removal performance and activated sludge characteristics in sequencing batch reactors.
Yujuan Chen,Huijun He,Hongyu Liu,Li Huiru,Guangming Zeng,Xing Xia,Chunping Yang,Chunping Yang +7 more
TL;DR: Results showed that salinity deteriorated the removal performance, activated sludge characteristics and microbial community in sequencing batch reactors (SBRs) and increased the extracellular polymeric substances (EPS) content ofactivated sludge, decreased the content of protein (PN) and loosely bound extraceocytes (LB-EPS), which led to better settleability of activatedSludge.

Various electron donors for biological nitrate removal: A review.
Yunmeng Pang,Jianlong Wang +1 more
TL;DR: A review of the state of the art of various electron donors used for biological denitrification can be found in this article, where a variety of electron donors including organic and inorganic compounds, including low-molecular-weight organics (e.g. acetate, methanol, glucose, benzene, methane, etc.), can be used for reducing NO3- pollution in water and wastewater.

Evaluation of wastewater treatment in a novel anoxic-aerobic algal-bacterial photobioreactor with biomass recycling through carbon and nitrogen mass balances.
Cynthia Alcántara,J. M. Domínguez,Dimas García,Saúl Blanco,Rebeca Pérez,Pedro A. García-Encina,Raúl Muñoz +6 more
TL;DR: Algal-bacterial symbiosis, implemented in an innovative anoxic-aerobic photobioreactor configuration with biomass recycling, supported an efficient removal of total organic carbon, inorganic carbon and total nitrogen during synthetic wastewater treatment at a hydraulic and sludge retention times of 2 days and 20 days, confirming the environmental sustainability of this innovative photobioresactor in terms of global warming impact.

Characteristics of heterotrophic/biofilm-electrode autotrophic denitrification for nitrate removal from groundwater
Shuang Tong,Baogang Zhang,Chuanping Feng,Yingxin Zhao,Nan Chen,Chunbo Hao,Jiaoyang Pu,Liwei Zhao +7 more
TL;DR: The developed HAD-BER would be a promising approach for nitrate removal from groundwater, indicating that there was synergistic interaction between the HDB and ADB, i.e., the organic carbon source used for denitrification could be decreased in the H AD-BER.
Journal ArticleDOI
Performance of a full-scale modified anaerobic/anoxic/oxic process: High-throughput sequence analysis of its microbial structures and their community functions.
TL;DR: The key functional microorganisms responsible for nitrification-denitrification in the WWTP were species belonging to the genera Nitrospira, Hydrogenophilaceae, Comamonas, Dechloromonas, Thauera, Haliangium, and Halomona, indicating that functional groups were highly enriched in the active sludges and thus enabled nitrogen removal.
